Title: Feature add validate for checksum of 10

If the final difference is 10, then the check digit becomes 0. To ensure that this does not happen, the standard recommends that serial numbers should not be used which produce a final difference of 10, however there are containers in the market which do not follow this recommendation, so handling this case has to be included if a check digit calculator is programmed.
