Pharmacy Controlled Substances and DEA Regulations 2

Question 1

A prescriber's DEA registration number is BC3234649. To verify it is valid using the check-digit method, what should the sum of the digits equal (mod 10)?

Accepted Answer

The last digit of the number (9)

Answer

DEA check digit: add digits 1+3+5, then add 2×(digits 2+4+6). Sum both. The last digit of the total should match the 7th digit of the DEA number. For BC3234649: (3+3+6)=12; 2×(2+4+4)=20; 12+20=32 → last digit 2? This example is illustrative — the principle is that the check digit confirms authenticity.
