27 ALGORITHM
28 1. The letter is replaced with a two-figure number appropriate to the
29 position of the letter in the german alphabet.
30
31 2. Beginning left all numbers are weighted with
32 2,1,2,5,7,1,2,1,2,1,2,1.
33
34 3. The the total of the digits of all products is computed.
35
36 4. The check digit is sum from 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.
