For example if the data "56789" is to be encoded as a barcode. The check digit is computed as follows.
Data | 5 | 6 | 7 | 8 | 9 |
Sum : | 5 + 6 + 7 + 8 + 9 = 35 | ||||
If Sum Mod 10 is 0, the result is 0. Otherwise the result is 10 - (Sum Mod 10) | |||||
Modulo 10 : | 10 - (35 % 10) = 5 | ||||
Data to be encoded | 567895 | ||||
Include Start and Stop characters | [567895] |
