Extended data:
ISBN refers to the international standard book number, which is an international number specially designed for identifying books and other documents. ISO promulgated the ISBN international standard in 1972, and set up the international ISBN center in the Prussian Library in West Berlin, which is the management institution for implementing the standard.
ISBN number consists of 13 digits, separated by four connecting digits or four spaces, and each group of digits has a fixed meaning.
ISBN is used in textbooks, printed matter, micro-reproduction, educational television or movies, mixed media publications, microcomputer software, atlases and maps, Braille publications and electronic publications.
According to ISO-2 108, the parity bit generation is calculated by the coefficient 1 1. The calculation method is to multiply the first nine digits of ISBN by numbers from 10 to 2 in turn, add the products, and divide the sum by11; If there is no remainder, the check number is "0"; If there is a remainder, subtract it from 1 1 and the difference is the check number. If the difference is 10, it is represented by an "x" representing the Roman numeral 10.
