Number check

1104144815 passes the NPI check digit test The final digit 5 matches the value computed from the first nine digits, so this is a well-formed NPI.
How the check works, step by step

Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.

Digit 8 0 8 4 0 1 1 0 4 1 4 4 8 1
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 1 0 4 2 4 8 8 2

Sum = 55 · next multiple of 10 = 60 · check digit = 5 · actual last digit = 5

A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
