Check digit in ISBN-13
Introduction:
From Jan 1, 2007 all ISBN will transfer from 10 digit to 13 digital.
The check digit algorithm of the check digit is also changed.
ISBN Check Digit Calculation
Introdutction:
The check digit is the last digit of an ISBN.
It is calculated on a modulus 11 with weights 10-2,
using X in lieu of 10 where ten would occur as a check digit.
This means that each of the first nine digits of the ISBN
– excluding the check digit itself –
is multiplied by a number ranging from 10 to 2 and
that the resulting sum of the products,
plus the check digit,
must be divisible by 11 without a remainder.
