Mathematic DEA formula

Question 1

To verify the legitimacy of a DEA number, you can use the following formula:

Add the first, third, and fifth digits together (sum A).

Add the second, fourth, and sixth digits together (sum B).

Answer 1

Multiply sum B by 2.

Add the results from sum A and the doubled sum of B.

The last digit of this total should match the seventh digit of the DEA number

Question 2

The first two letters of a DEA (Drug Enforcement Administration) number correspond to the registrant’s type. Here are some common examples:
A for practitioners (doctors, dentists, etc.)
B for hospitals or clinics
F for mid-level practitioners (nurse practitioners, physician assistants)
M for manufacturers
P for distributors
R for researchers
For example, if you’re checking a DEA number for a doctor, it would start with “A.” Keep in mind that this is just a general guideline, and there might be exceptions. Always verify with official sources
