Check Digit Verification of cas no

The CAS Registry Mumber 78727-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,2 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78727-98:
(7*7)+(6*8)+(5*7)+(4*2)+(3*7)+(2*9)+(1*8)=187
187 % 10 = 7
So 78727-98-7 is a valid CAS Registry Number.

Cycloadditions dipolaires 1,3 aux derives nitres α ethyleniques, acetyleniques potentiels. I. Reaction avec des ylures d'azomethine. Orientation et stereochimie de la cycloaddition

Benhaoua, Hadj,Piet, Jean-Claude,Danion-Bougot, Renee,Toupet, Loic,Carrie, Robert

, p. 325 - 338 (2007/10/02)

The stereochemistry of the nitroolefins 1 prepared by known methods was unambigously established.Their reactions with azomethine ylides (e.g. 8) was studied and the stereochemistry of the adducts as well.This preliminary work was necessary to substantiate a discussion of structural (pyrrolidines conformational analysis) and mechanistic problems (dipolarophile-azomethine ylide approach and HNO2 elimination from the nitro pyrrolidines).
