Structural rules

Check digit calculation
Letters are converted into numbers beginning with B = 11 and ending at Z = 35. However, vowels are not used, they are not skipped according to the sequence: B = 11, C = 12, D = 13, F = 15 (letter E is not used). Then, provide weights to the following digits and then index: All the products are then added up, then the sum is divided by 10 and the remainder is the check digit.

For example, we have the ID of FHXXXBXFVFMXM and the check digit will be calculated as follows: All products sum up to 1566 and 1566 divided by 10 is 156 remainder 6 so the check digit is 6. The completed Will Turner Telfords Code example above is FHXXXBXFVFMXM6.
