NAME

CheckDigits::M97_001 - compute check digits for VAT Registration Number (BE)

CONTENTS

SYNOPSIS



  use Algorithm::CheckDigits;

  $ustid = CheckDigits(ustid_be);

  if ($ustid->is_valid(136695962)) {
        # do something
  }

  $cn = $ustid->complete(1366959);
  # $cn = 136695962

  $cd = $ustid->checkdigit(136695962);
  # $cd = 62

  $bn = $ustid->basenumber(136695962);
  # $bn = 1366959



DESCRIPTION

    ALGORITHM

1. The whole number (without checksum) is taken modulo 97.
2. The checksum is difference of the remainder from step 1 to 97.

    METHODS

is_valid($number) Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given above.

Returns false otherwise,

complete($number) The check digit for $number is computed and concatenated to the end of $number.

Returns the complete number with check digit or ’’ if $number does not consist solely of digits and spaces.

basenumber($number) Returns the basenumber of $number if $number has a valid check digit.

Return ’’ otherwise.

checkdigit($number) Returns the checkdigits of $number if $number has a valid check digit.

Return ’’ otherwise.

    EXPORT

None by default.
