Number check

1649532631 passes the NPI check digit test The final digit 1 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 6 4 9 5 3 2 6 3
Doubled? — ×2 — ×2 — ×2 — ×2 — ×2 — ×2 — ×2
Value 8 0 8 8 0 2 6 8 9 1 3 4 6 6

Sum = 69 · next multiple of 10 = 70 · check digit = 1 · actual last digit = 1

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.
