DESCRIPTION

28   ALGORITHM
29       1.  Beginning right all numbers are weighted alternatively 1 and 2.
30
31       2.  The total of the digits of all products is computed.
32
33       3.  The sum of step 3 ist taken modulo 10.
34
35       4.  The check digit is the difference between 10 and the number from
36           step 3 taken modulo 10.
37
38   METHODS
39       is_valid($number)
40           Returns true only if $number consists solely of numbers and the
41           last digit is a valid check digit according to the algorithm given
42           above.
43
44           Returns false otherwise,
45
46       complete($number)
47           The check digit for $number is computed and concatenated to the end
48           of $number.
49
50           Returns the complete number with check digit or '' if $number does
51           not consist solely of digits and spaces.
52
53       basenumber($number)
54           Returns the basenumber of $number if $number has a valid check
55           digit.
56
57           Return '' otherwise.
58
59       checkdigit($number)
60           Returns the checkdigit of $number if $number has a valid check
61           digit.
62
63           Return '' otherwise.
64
65   EXPORT
66       None by default.
