Note about Brazilian CPF/CNPJ generation algorithm: In this software, valid means that the analyzed string conforms to the Brazilian CPF/CNPJ generation algorithm. This software does not make any verification in the records of the Brazilian Government. Therefore, it is possible that a valid string has not been issued by the Brazilian Government.
