140668-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140668-84-4 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 140668-84:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*8)+(2*8)+(1*4)=134
134 % 10 = 4
So 140668-84-4 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 (1992)

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.
