Check Digit Verification of cas no

The CAS Registry Mumber 114049-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,4 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 114049-86:
(8*1)+(7*1)+(6*4)+(5*0)+(4*4)+(3*9)+(2*8)+(1*6)=104
104 % 10 = 4
So 114049-86-4 is a valid CAS Registry Number.

Reactions of Diene-conjugated 1,3-Dipolar Intermediates: A Versatile and Efficient Route to Dibenzazepines via Benzonitrile o-Arylbenzyl Ylides

Cullen, Kevin E.,Sharp, John T.

, p. 2961 - 2968 (2007/10/02)

Diene-conjugated nitrile ylides of the type 1 in which both the α,β- and the γ,δ-double bonds are aromatic and where R is either hydroger or a para substitutent, cyclise to give dibenzazepines21 (Scheme 2) in high yield.This is in contrast to the analogous diazo system 2 in which cyclisation do not occur.The presence of an ortho methyl group in the ring under attack (1j, Scheme 3) prevents cyclisation via its steric limitations of conjugation in the transition state.
