NPI Validation Check Digit Calculation
The following table explains the step by step NPI number validation process using the ISO standard Luhn algorithm.
|Start with the original NPI number, the last digit is the check digit and is not used in the calculation.|
|Step 1: Double the value of the alternate digits, beginning with the rightmost digit.|
|Step 2: Add all the doubled and unaffected individual digits from step 1 plus the constant number 24.|
|2 + 0 + 0 + 3 + 0 + 1 + 0 + 7 + 8 + 24 = 45|
|Step 3: Subtract the total obtained in step 2 from the next higher number ending in zero, the result is the check digit.|
|50 - 45 = 5||5|
The NPI number 1003010745 is valid because the calculated check digit 5 using the Luhn validation algorithm matches the last digit of the original NPI number.
