MOD 7 Check Digit - The check digit is the last or ninth number of the PRO number. The first eight numbers are in sequence.
Example: XXX-XXXXXC (PRO number), C = Check digit
The check digit, or ninth number, will be 0 through 6, and will never exceed 6.
The check digit is determined or verified by dividing the first eight digits by seven. The remainder of this division is the check digit.
Examples: Using a calculator, divide the PRO number minus the check digit by seven. The decimal remainder will determine the check-digit number.
The following table shows the check digit of each decimal remainder when dividing by seven:
| Check Digit | Remainder |
|---|---|
| 0 (zero) | none |
| 1 | .14 |
| 2 | .28 or .29 |
