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.

1044

40

4

5.Subtract the remainder from the modulus.

The result becomes the check digit. In this case, the check digit is 6.

10 - 4 = 6
