NFE-253
Rejeição: Digito Verificador da chave de acesso composta inválida (cDV …, calculado …).
In English cDV is not the modulo 11 check digit of the 43 digits of the access key (weights 2 to 9 from the right, 0 when the result is 10 or 11).
What the rule checks
As the rule set's publisher wrote it. The rule runs on every element the context matches, and fails where the test is false; the validator reports the line of that element.
