What is the total of the first step and second step in validating a DEA number?

To validate a DEA (Drug Enforcement Administration) number, the process involves a specific calculation that results in a number that corresponds to the last digit of the DEA number. The DEA number consists of a series of letters and numbers that follow a unique structure.

In the first step, you sum the digits in the odd positions (the first, third, and fifth digits). In the second step, you sum the digits in the even positions (the second, fourth, and sixth digits), then multiply that sum by 2. The final step requires adding the results of the two calculations together. The total of this addition will be equal to the last digit of the DEA number.

This systematic approach ensures that the DEA number adheres to a standardized format, helping to identify valid registrations and prevent fraudulent numbers. Thus, the correct answer reflects the fundamental validation rule that the total calculated must match the last digit of the DEA number, ensuring that this number is authentic and follows the designated structure.
