Ohio Multistate Pharmacy Jurisprudence Examination (MPJE) Practice Test

The validity of a DEA number can be determined by checking specific criteria established by the Drug Enforcement Administration (DEA). A DEA number typically consists of two letters followed by seven digits. The first letter represents the type of registrant (e.g., 'A' for practitioners), the second letter represents the first letter of the registrant's last name, and the remaining digits contribute to the number's check digit.

In the case of the DEA number provided, AB2456726, the first letter 'A' indicates it is assigned to a practitioner, which is appropriate. However, the second letter should correspond to the first letter of Dr. Brody's last name. If Dr. Brody's last name does not begin with 'B,' then the number is not valid for him, as the second letter must match that of the practitioner's last name to be appropriate for their use.

Additionally, the last digit of the DEA number is a check digit calculated from the preceding digits; if this check does not validate correctly, the number is invalid.

Therefore, if Dr. Brody's last name does not start with 'B' or if the last digit fails the verification process, then it confirms that the DEA number is not valid for Dr
