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:

field:	5	2	3	2	4	5	2	1	9
weight string:	4	1	2	3	4	1	2	3	4
products:	20	2	6	6 16		5	4	3 36

3.Next, the digits of the products are added together. Two-digit products are treated as two separate digits.

This is the sum of the digits.

2 + 0 + 2 + 6 + 6 + 1 + 6 + 5 + 4 + 3 + 3 + 6 = 44

4.Divide the sum of the digits by the modulus (10 in this case), only to the whole number. The balance is called the remainder.
