Check Digit Verification of cas no

The CAS Registry Mumber 873222-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,2,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 873222-80:
(8*8)+(7*7)+(6*3)+(5*2)+(4*2)+(3*2)+(2*8)+(1*0)=171
171 % 10 = 1
So 873222-80-1 is a valid CAS Registry Number.

Copper-catalyzed oxygenation of 3-hydroxy-2-phenylquinolin-4(1H)-one: Synthesis, structure and spectral properties of [Cu(idpa)(N-baa)]ClO 4, [idpa = 3,3′-iminobis(N,N-dimethylpropylamine), N-baaH = N-benzoylanthranilic acid]

, p. 813 - 816 (2005)

Reaction of one molar equivalent of 3,3′-iminobis(N,N- dimethylpropylamine (idpa)), N-benzoylanthranilic acid (N-baaH) and [Cu(CH 3CN)4](ClO4) in acetonitrile resulted in the formation of a stable ionic copper(II) complex without additional solvent coordination. The composition and molecular structure of [Cu(idpa)(N-baa)] ClO4 was fully determined by IR, UV-vis, and X-ray crystal analysis. The complex has a distorted square planar CuN3O core. The oxygenation of 3-hydroxy-2-phenylquinolin-4(1H)-one (QuinH2) using [Cu(idpa)(N-baa)]ClO4 as a catalyst results in the oxidative cleavage of the heterocyclic ring to give a N-benzoylanthranilic acid and CO as a mimic of quercetinase and 3-hydroxy-1,4-dihydroquinolin-4-one 2,4-dioxygenase action.
