This ISBN-10
can be converted to an ISBN-13 using the following steps:
The calculation of an ISBN-13 check digit begins with the first 12 digits of the thirteen-digit ISBN (thus excluding 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 (0) replaces a ten (10), so, in all cases, a single check digit results.
s = 9×1 + 7×3 + 8×1 + 0×3 + 8×1 + 2×3 + 8×1 + 8×3 + 2×1 + 5×3 + 8×1 + 6×3 = 9 + 21 + 8 + 0 + 8 + 6 + 8 + 24 + 2 + 15 + 8 + 18 = 127 127 / 10 = 12 remainder 7 10 – 7 = 3
This ISBN-13:
can be converted to an ISBN-10 using the following steps:
Each of the first nine digits of the ten-digit ISBN — excluding the check digit, itself — is multiplied by a number in a sequence from 10 to 2, and the remainder of the sum, with respect to 11, is computed. The check digit is 11 minus the remainder.
s = 0x10 + 8x9 + 2x8 + 8x7 + 8x6 + 2x5 + 5x4 + 8x3 + 6x2 = 0 + 72 + 16 + 56 + 48 + 10 + 20 + 24 + 12 = 258 258 / 11 = 23 remainder 5 11 - 5 = 6
