  • 5 out of 5 stars - Review by lanning ***** on January 14, 2026

    Dr. Moiseiwitsch provides a superb professional service and is, beyond that, pleasant to deal with. He is careful and thorough, offers good explanations of alternatives and possibilities. I've never had the least qualm about working with him in what is definitely not a fun procedure. My history with this doctor includes two root canals. I can compare those with other dentists I've seen for others

  • NPI NPI Number Validation

    How NPI Validation Works

    The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.

    To verify the NPI 1821250861, we treat the final digit (1) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 59. The final step is to find the difference between that total and the next multiple of ten (60 - 59 = 1).

    Digit-by-digit view

    Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.

    Step 1: Double every other digit from the right

    Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.

    1 → 2 2 → 4 2 → 4 0 → 0 6 → 12 → 3

    Step 2: Add all digits plus the NPI constant

    Add the transformed values, the unchanged digits, and the constant 24.

    2 + 8 + 4 + 1 + 4 + 5 + 0 + 8 + 1 + 2 + 24 = 59

    Step 3: Find the amount needed to reach the next multiple of 10

    The next multiple of ten after 59 is 60. The difference is the calculated check digit.

    60 - 59 = 1
    This NPI is valid
    The calculated check digit is 1, which matches the last digit of 1821250861.
