Paxar 9401 manual Sum of Digits

9401/9402 System Administrator's Guide

When assigning weights, do not use the same number throughout. Also, do not assign a weight to the check digit.

4	3	8	2	7	C
6	5	4	3	2

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.

4	3	8	2	7	C
6	5	4	3	2
24	15	32	6	14

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
