Check Digit Verification of cas no

The CAS Registry Mumber 1278520-82-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,8,5,2 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1278520-82:
(9*1)+(8*2)+(7*7)+(6*8)+(5*5)+(4*2)+(3*0)+(2*8)+(1*2)=173
173 % 10 = 3
So 1278520-82-3 is a valid CAS Registry Number.

Formation of CuI(CH3CN)4ClO4 in the reactions of copper(II) perchlorate with acetonitrile in the presence of sulfur-containing organic compounds

Beloglazkina,Shimorsky,Mazhuga,Shilova,Tafeenko,Zyk

experimental part, p. 1504 - 1508 (2009/12/04)

Cu(ClO4)2?6H2O was shown to react with 2,2?-[propane-1,3-diylbis(thio-2-phenylnemethylidene]-bis(3-pyridylamine) (I) or (5Z)-2-ethoxycarbonylmethyl-(2-pyridylmethylidene)-3,5-dihydro-4H- imidazol-4-one (II) in the presence of CH3CN with the reduction of copper(II) to copper(I) and the formation of the tetrahedral complex Cu I(CH3CN)4ClO4 (III). In the course of the reaction the organic ligands I and II were oxidized to the corresponding sulfoxides.
