How this is calculated
Citation
DEA Pharmacist's Manual (2022): practitioner numbers begin A, B, F or M, then almost always the last-name initial and seven digits. DEA publishes no check digit; Gabay, Hosp Pharm 2013, states the formula, which DEA's example MJ3614511 satisfies. Read the sources: DEA Pharmacist's Manual ↗, Gabay 2013 ↗
