OCR Check Digit Calculation
- Multiply each digit by a weight pattern of 2, 1, 2, 1, 2.
- If the product is two digits, add the two digits together.
- Now add all digits together .
- Take the sum and subtract from the next multiple of ten.
- The result is the check digit.
Example: Filing Frequency 30408
- 3 X 2 = 6
0 X 1 = 0
4 X 2 = 8
0 X 1 = 0
8 X 2 = 16 - Since the product of 7 X 2 is two digits, add the two digits : 1 + 6 = 7
- 6 + 0 + 8 + 0 + 7 = 21
- 30 - 21 = 9
- 9 is the check digit for for the Filing Frequency 30408.
- 3 X 2 = 6
