Suspicious translation from old evco-id to new ema-id

[inbrain]

NL-TNM-009637-9 is parsed as NL-TNM-000096379-M but check digit was not taken into account at all. Maybe it's wrong?

According to specification:
contract IDs as defined in DIN SPEC 91286 may be used as well by adding two zeros (”00”) at the beginning of the Instance-part and the old check digit at position 14. A second check digit may be calculated over the resulting ID and may be added on position 15. (algorithm of check digit calculation for ISO 15118-1 Contract IDs is described here: here: http://www.ochp.eu/id-validator/e-mobility-ids_evcoid_check-digit-calculation_explanation/)
Example: The DIN-Contract-ID DE-8AA-123A56-3 must be set as EMAID DE- 8AA-00123A563-N.
