If a DEA number starts with AD380410, what is the final number?

  1. 6

  2. 7

  3. 8

  4. 9

The correct answer is: 8

To determine the final number of a DEA number, you must use a specific calculation involving the first six digits of the DEA number. The DEA number is structured to include an identifier for the registrant and a specific check digit at the end to verify the validity of the number. To calculate the check digit, follow these steps: 1. Identify the odd positions (1st, 3rd, 5th) and even positions (2nd, 4th, 6th) from the DEA number. For the DEA number AD380410: - Odd positions: A (1), 3, 0, 0 - Even positions: D (2), 8, 4, 1 2. Assign numerical values to the letters. For instance, the letter 'A' is assigned the number 1, 'B' the number 2, and so forth. 3. Calculate the sum of the numbers in the odd positions: - Odd position calculation: 1 (for A) + 3 + 0 + 0 = 4. 4. Calculate the sum of the numbers in the even positions, and then multiply that sum by 2: - Even position calculation:
