Check Digit Verification of cas no

The CAS Registry Mumber 928312-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,3,1 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 928312-23:
(8*9)+(7*2)+(6*8)+(5*3)+(4*1)+(3*2)+(2*2)+(1*3)=166
166 % 10 = 6
So 928312-23-6 is a valid CAS Registry Number.

Organocatalytic cascade reactions based on push-pull dienamine platform: Synthesis of highly substituted anilines

Ramachary, Dhevalapally B.,Ramakumar, Kinthada,Narayana, Vidadala V.

, p. 1458 - 1463 (2007)

(Chemical Equation Presented) A practical and novel one-pot organocatalytic selective process for the cascade synthesis of highly substituted o-hydroxydiary lamines and o-pyrrolidin-1-yldiarylamines is reported. Direct combination of amine-catalyzed cascade Knoevenagel/Michael/aldol condensation/decarboxylation and cascade enamine amination/isoaromatization of alkyl acetoacetates, aldehydes, and nitrosoarenes furnished the highly functionalized anilines with high yields.
