Check Digit Verification of cas no

The CAS Registry Mumber 140668-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,6 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140668-83:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*8)+(2*8)+(1*3)=133
133 % 10 = 3
So 140668-83-3 is a valid CAS Registry Number.

The Benzene Ring as a Dipolarophile: Reactions of Monosubstituted Benzenes with Tetracyanoethylene Oxide

Hoz, A. de la,Pardo, C.,Elguero, J.,Jimeno, M. L.

, p. 99 - 104 (2007/10/02)

The reaction of tetracyanoethylene oxide on one hand and toluene, chlorobenzene, fluorobenzene, anisole, and nitrobenzene, on the other, has been studied.Toluene and the halogenobenzenes yield mixtures of monoadducts, anisole yield p-methoxyphenylmalononitrile and its dimer and nitrobenzene does not react.These results are discussed with the help of a qualitative orbital model. 1H-NMR analysis of some monoadducts has been carried out.Keywords: Benzene derivatives; Tetracyanoethylene oxide; 1,3-Dipolar cycloaddition.
