these 10 digits consist of blocks identifying the language, the publisher, the number assigned to the book by its publishing company, and finally, a 1-digit check digit that is either a digit or the letter x (used to represent 10).
this check digit is selected so that â10i=1ixiâ¡0 mod 11 and is used to detect errors in individual digits and transposition of digits.
