OCR Check Digit Calculation

  1. Multiply each digit by a weight pattern of 2, 1, 2, 1, 2.
  2. If the product is two digits, add the two digits together.
  3. Add all digits together.
  4. Take the sum and subtract from the next multiple of ten.
  5. The result is the check digit.

Example: Filing Frequency 10818

  1. 1 X 2 = 2
    0 X 1 = 0
    8 X 2 = 16*
    1 X 1 = 1
    9 X 2 = 18**
  2. *Since the product of 8 X 2 is two digits, add the two digits : 1 + 6 = 7
    **Since the product of 9 X 2 is two digits, add the two digits : 1 + 8 = 9
  3. 2 + 0 + 7 + 1 + 9 = 19
  4. 20 - 19 = 1
  5.  1 is the check digit for the filing frequency 10818
