3. Assign a number from 2 to 10 as the
modulus
. The
modulus will be used in the check digit calculation.
Modulus = 10
4. Multiply each digit in the field by its corresponding weight
digit.

5. Find the sum of all the products.
24 + 15 + 32 + 6 + 14 = 91
6. Calculate the first multiple of the modulus that is greater
than the sum of the products.
10 x 10 = 100 ( >91)
7. Subtract the sum of the products from this number.
100 - 91 = 9
8. The resulting number is the check digit.
Check digit = 9
