Description:

In Brazil there is a CPF (Cadastro de Pessoas Físicas) number which serves to identify each individual in the country. The number composes of eleven numeric digits, being the two last ones the checking digits.

The function calculates the two checking digits, based on the nine preceding digits.

Input:

the eleven numeric digits for a CPF number

Output:

-3 (parameter is empty)

-2 (number of digits <> 11)

-1 (incorrect entry)

1 (OK)

Examples:

lnput: Validate_CPF (12345678909)

Output: 1

lnput: Validate_CPF ("123.456.789-09")

Output: 1

You can modify the Case result numbers to return a Boolean calculation, so that the function could be tested as GetAsBoolean ( Validate_CPF (_Num) ).
