This is a description of calculating check digits according to Modulo 16.
Calculation of a checksum according to Modulo 16:
Modulo 16 is used by the barcode symbology Codabar. Here is an example of how to calculate the check digit according to Modulo 16:
Reference numbers:
Modulo 16 is used by the barcode symbology Codabar. Here is an example of how to calculate the check digit according to Modulo 16:
| Digits: | A 7 8 9 A |
| Reference numbers: | 16 7 8 9 16 |
| Sum of reference numbers: | 56 |
| Calculate checksum: | 56 / 16 = 3 Remainder 8 |
| difference: | 16 - 8 = 8 |
| Check digit | Reference number 8 = 8 |
