49-627: The Biological Stain Commission (BSC) is an organization that provides third-party testing and certification of dyes and a few other compounds that are used to enhance contrast in specimens examined in biological and medical laboratories. The BSC is a century-old organization well known to many thousands of scientists, worldwide but especially in N America, who buy BSC-certified stains for staining microscopic preparations and for making selective culture media for bacteria . Manufacturers and other vendors submit samples from their batches of dyes to

The International ISBN Agency sometimes assigns ISBNs to such books on its own initiative.

Since 1 January 2007, ISBNs have contained thirteen digits, a format that is compatible with " Bookland " European Article Numbers , which have 13 digits. Since 2016, ISBNs have also been used to identify mobile games by China's Administration of Press and Publication . The United States , with 3.9 million registered ISBNs in 2020,

In December 2018 the BSC added to its website an online glossary of hundreds of words and short phrases used in the field of biological staining. This was revised and enlarged in 2021 and 2023. The annual meetings of the BSC are usually held on the first or second weekend in June, in cities easily accessible by air from major centers in North America and Europe. These meetings include scientific sessions with presentations by invited speakers in such disciplines as cancer biology, neuroscience, pathology and plant sciences. There are also informal presentations and exchanges of information among academic biologists, medical scientists, pathologists, and representatives of companies that manufacture and sell biological stains. The invited presentations planned for meetings in 2020 and 2021 were postponed because of
245-451: A given ISBN is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for that country or territory regardless of the publication language. The ranges of ISBNs assigned to any particular country are based on the publishing profile of the country concerned, and so
294-401: A systematic pattern, which allows their length to be determined, as follows: A check digit is a form of redundancy check used for error detection , the decimal equivalent of a binary check bit . It consists of a single digit computed from the other digits in the number. The method for the 10-digit ISBN is an extension of that for SBNs, so the two systems are compatible; an SBN prefixed with
343-461: A zero (the 10-digit ISBN) will give the same check digit as the SBN without the zero. The check digit is base eleven, and can be an integer between 0 and 9, or an 'X'. The system for 13-digit ISBNs is not compatible with SBNs and will, in general, give a different check digit from the corresponding 10-digit ISBN, so does not provide the same protection against transposition. This is because the 13-digit code
392-564: A zero to a 9-digit SBN creates a valid 10-digit ISBN. The national ISBN agency assigns the registrant element ( cf. Category:ISBN agencies ) and an accompanying series of ISBNs within that registrant element to the publisher; the publisher then allocates one of the ISBNs to each of its books. In most countries, a book publisher is not legally required to assign an ISBN, although most large bookstores only handle publications that have ISBNs assigned to them. The International ISBN Agency maintains

Let Then This check system—similar to the UPC check digit formula—does not catch all errors of adjacent digit transposition. Specifically, if the difference between two adjacent digits is 5, the check digit will not catch their transposition. For instance, the above example allows this situation with

In 1965, British bookseller and stationers WHSmith announced plans to implement a standard numbering system for its books.

The first version of the ISBN identification format was devised in 1967, based upon the 9-digit Standard Book Numbering ( SBN ) created in 1966. The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108 (any 9-digit SBN can be converted to

It is possible to avoid the multiplications in a software implementation by using two accumulators. Repeatedly adding t into s computes the necessary multiples: The modular reduction can be done once at
735-414: Is rendered The two most common errors in handling an ISBN (e.g. when typing it or writing it down) are a single altered digit or the transposition of adjacent digits. It can be proven mathematically that all pairs of valid ISBN-10s differ in at least two digits. It can also be proven that there are no pairs of valid ISBN-10s with eight identical digits and two transposed digits (these proofs are true because

By prefixing a zero, this can be converted to ISBN 0-340-01381-8 ; the check digit does not need to be re-calculated. Some publishers, such as Ballantine Books , would sometimes use 12-digit SBNs where the last three digits indicated the price of the book; for example, Woodstock Handmade Houses had
833-448: The 13-digit ISBN, as follows: A 13-digit ISBN can be separated into its parts ( prefix element , registration group , registrant , publication and check digit ), and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts ( registration group , registrant , publication and check digit ) of a 10-digit ISBN is also done with either hyphens or spaces. Figuring out how to correctly separate
882-432: The 6 followed by a 1. The correct order contributes 3 × 6 + 1 × 1 = 19 to the sum; while, if the digits are transposed (1 followed by a 6), the contribution of those two digits will be 3 × 1 + 1 × 6 = 9 . However, 19 and 9 are congruent modulo 10, and so produce the same, final result: both ISBNs will have a check digit of 7. The ISBN-10 formula uses the prime modulus 11 which avoids this blind spot, but requires more than
931-473: The 978-prefix element are: 0 or 1 for English-speaking countries; 2 for French-speaking countries; 3 for German-speaking countries; 4 for Japan; 5 for Russian-speaking countries; and 7 for People's Republic of China. Example 5-digit registration groups are 99936 and 99980, for Bhutan. The allocated registration groups are: 0–5, 600–631, 65, 7, 80–94, 950–989, 9910–9989, and 99901–99993.

The original 9-digit standard book number (SBN) had no registration group identifier, but prefixing

1519-466: The check digit itself). Each digit, from left to right, is alternately multiplied by 1 or 3, then those products are summed modulo 10 to give a value ranging from 0 to 9. Subtracted from 10, that leaves a result from 1 to 10. A zero replaces a ten, so, in all cases, a single check digit results. For example, the ISBN-13 check digit of 978-0-306-40615- ? is calculated as follows: Thus, the check digit

1568-419: The check digit must equal either 0 or 11. Therefore, the check digit is (11 minus the remainder of the sum of the products modulo 11) modulo 11. Taking the remainder modulo 11 a second time accounts for the possibility that the first remainder is 0. Without the second modulo operation, the calculation could result in a check digit value of 11 − 0 = 11 , which is invalid. (Strictly speaking, the first "modulo 11"
1617-773: The commission's web site. A BSC-certified stain rarely costs more than a non-certified one with the same name. The BSC is a non-profit organization, incorporated in the State of New York, for the purpose of ensuring a supply of high quality stains (mostly dyes) for use in biological and medical laboratories. Its origins date from 1922, when vendors of biological stains in the USA had exhausted their stocks of pre-war dyes imported from Germany. American dye manufacturers at that time were unable to produce products that were consistently reliable in histological microtechnique and bacteriology (Conn 1980–1981; Penney 2000).

Biological Stains , a book about the chemistry, testing and applications of dyes and other colorants in biology and medicine, has been published by the BSC since 1925. The first seven editions (1925-1961) were by H. J. Conn. The eighth and ninth editions (1969, 1977), retitled Conn's Biological Stains , were by Ralph Dougall Lillie, who added many dyes and chromogenic reagents and provided extensive tables of data for classification, nomenclature and solubilities of dyes.

In contrast, it is possible for other types of error, such as two altered non-transposed digits, or three altered digits, to result in a valid ISBN (although it is still unlikely).
