Taxonomy Description
Chiropractic Nutrition is that specialty within the chiropractic profession that deals with the overall factors that affect the patient's ability to maintain the manipulative correction and thus sustain better neurological integrity. The Chiropractic Nutrition Specialist will perform extensive research on the patient's previous health history, ethnicity, and any family history related to what the patient is being treated for. Patients fill out questionnaires concerning dietary and sleep patterns and previous or present symptomology. A nutrition examination would be performed to assess areas such as absorption rates, adrenal function, kidney health, lung health etc. The patient is often instructed on how to check the pH of their saliva and urine, test for the presence of Candida Albicans, etc., at home. Outside laboratory testing includes blood, urine, hair analysis, food allergy testing etc. The patient's prescription and over the counter medications are recorded and analyzed.

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 1053926790, we treat the final digit (0) 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 60. The final step is to find the difference between that total and the next multiple of ten (60 - 60 = 0).

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 5 → 10 → 1 9 → 18 → 9 6 → 12 → 3 9 → 18 → 9

Step 2: Add all digits plus the NPI constant

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

2 + 0 + 1 + 0 + 3 + 1 + 8 + 2 + 1 + 2 + 7 + 1 + 8 + 24 = 60

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

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

60 - 60 = 0
This NPI is valid
The calculated check digit is 0, which matches the last digit of 1053926790.
