West Virginia MPJE (Pharmacy Jurisprudence) Practice Exam

What is the method for verifying the validity of a DEA number?

1. Add the 1st, 3rd, and 5th digits together, add the 2nd, 4th, and 6th digits and multiply by 2, then check the last digit

2. Add the 1st, 2nd, and 3rd digits together and multiply by 2, then add the remaining digits

3. Add the 1st, 3rd, and 5th digits, add the 2nd, 4th, and 6th digits, then subtract from 100

4. Calculate the sum of all digits and check if it is divisible by 7

The correct answer is: Add the 1st, 3rd, and 5th digits together, add the 2nd, 4th, and 6th digits and multiply by 2, then check the last digit

The method for verifying the validity of a DEA number is indeed to add the 1st, 3rd, and 5th digits together, then add the 2nd, 4th, and 6th digits and multiply this sum by 2, and finally, check if the last digit of the resulting total matches the last digit of the DEA number itself. This process utilizes a specific pattern to confirm that the DEA number has been assigned correctly. The first set of digits (1st, 3rd, and 5th) is added together to secure a subtotal, while the second set (2nd, 4th, and 6th) is added together and multiplied by two, which helps to introduce variation in the resultant number. The final step is determining if the last digit of this calculation corresponds with the last digit of the original DEA number, which serves as a check against potential errors in the number generation. This method is designed to catch errors that might occur in the transcription of the number and provides a systematic approach for healthcare professionals to ensure they are working with valid DEA numbers when handling controlled substances. It's essential for maintaining compliance with legal regulations guiding the prescribing and dispensing of medications classified as controlled substances.
