C- 308
Example: 2 + 14 + 18 + 20 + 20 + 18 + 14 = 106
4 Divide the sum from step 3 by 11.
Example: 106 divided by 11 is 9 with a remainder of 7.
If the remainder is 0, the self-check digit is 0. If the remainder is 1, your number does not have a modulus
11 self-check digit, and you should not use the number in the fields you define with modulus 11 self-check
fields.
5 Subtract the remainder obtained in step 4 from 11 to obtain the self-check digit.
Example: The remainder from step 4 is 7; 11 minus 7 is 4, which is the self-check digit.
