Check Digit Verification of cas no

The CAS Registry Mumber 111183-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,1,8 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 111183-80:
(8*1)+(7*1)+(6*1)+(5*1)+(4*8)+(3*3)+(2*8)+(1*0)=83
83 % 10 = 3
So 111183-80-3 is a valid CAS Registry Number.

1,5-Dicarbonyl Compounds via Michael-Addition of Deprotonated Enamines and Allylamines to 2-(N-Methylanilino) acrylonitrile

Ahlbrecht, Hubertus,Dietz, Manfred,Weber, Lothar

, p. 251 - 254 (2007/10/02)

A new method for the synthesis of the title compounds by a onepot, three component, coupling reaction is described.Is consists of the reaction of a homoenolate anion and an enol cation equivalent with subsequent alkylation of an acyl-anion equivalent.Hence the methodology of Umpolung is used in a threefold manner within the reaction sequence.
