Does anyone know how the NPI checksum works?

[http://www.barrydebruin.com/php/npi/ Try this website. It's a free NPI check digit(checksum) tool for the health care industry]


 * Note: The above page only checks 9-digit numbers. The NPI is 10 digits long.


 * update Feb 9, 2008 - The NPI number uses the Luhn forumla to calculate. You put in 9 numbers, it runs through an algorithm (google it), and generates the 10th digit, which is a check digit used for validation.


 * This needs a citation .... Anyone? --Mistsrider (talk) 19:58, 19 January 2011 (UTC)
