3.
Next, the product of each digit is added together. This is the
sum of the products.
20 + 2 + 6 + 6 + 16 + 5 + 4 + 3 + 36 = 98
4.
Divide the sum of the products by the modulus ( 10 in this
case), only to the whole number. The balance is called the
remainder.

5. Subtract the remainder from the modulus.
The result becomes the check digit. In this case, the check
digit is
2 .
10 - 8 = 2

This is an example of how the printer uses Sum of Digits to
calculate a check digit for this data:
5 2 3 2 4 5 2 1 9
1. Weights are applied to each digit, starting with the last digit in
the weight string. They are applied right to left, beginning at
the right-most position of the field. Remember, a weight
string must contain at least two different numbers. This
example has a weight string of
1,2,3,4 :
field: 5 2 3 2 4 5 2 1 9
weight string:
4 1 2 3 4 1 2 3 4
2. Each digit in the field is multiplied by the weight assigned to it:
