The various coupling-constant-dependent numbers describing anomalous commutators are constrained by the nonrenormalization of the axial-vector-current anomaly. The axial-vector current continues to behave anomalously even if the underlying unrenormalized field theory is finite due to the vanishing of the Gell-Mann-Low eigenvalue function.
