What should the last digit be of this DEA number? AB431762__

One
Three
Five
Seven

The correct answer is: Five

To determine the last digit of a DEA number, a specific algorithm is used that ensures the number is valid. The DEA number format consists of two letters followed by seven digits. The first letter represents the type of registrant (such as a physician or pharmacy), the second letter identifies the first letter of the registrant's last name, and the remaining seven digits are a unique identifier. To verify the last digit, follow these steps: 1. Take the first, third, and fifth digits of the DEA number and add them together. 2. Take the second, fourth, and sixth digits of the DEA number, multiply that sum by 2. 3. Add the results of step 1 and step 2. 4. The last digit of the total (from step 3) will be the same as the last digit of the DEA number. For the provided DEA number AB431762__, we can identify the digits: - 1st, 3rd, and 5th: 4, 1, 7 - 2nd, 4th, and 6th: 3, 6, 2 Calculating: - Sum of 1st, 3rd, and 5th
