Validate Credit Card

[Dan]

Hello All,
 
Could some one give me some ideas on how to validate a Credit Card
number.  I would like to use a perl module but for every windows perl
module such as Business-CreditCard I get the following error.
 
Error installing package 'Business-OnlinePayment': Read a PPD for
'Business-OnlinePayment', but it is not intended for this build of Perl
(MSWin32-x86-multi-thread)
 
I tried doing this from a window command prompt i.e ppm> install
Business-OnlinePayment.
 
Any ideas?
 
Regards,
 
Dan
