Sum of Digits Calculation
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
