Check Digit Verification of cas no

The CAS Registry Mumber 477335-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,3,3 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 477335-92:
(8*4)+(7*7)+(6*7)+(5*3)+(4*3)+(3*5)+(2*9)+(1*2)=185
185 % 10 = 5
So 477335-92-5 is a valid CAS Registry Number.

Pyrrolizine and indolizine derivatives from 1,6-dioxo-2,4-diene by inter- and intramolecular ring closure

Ong, Chi Wi,Lai, Ming Chih,Jan, Jing Jyh,Chang, Yu An

, p. 1303 - 1311 (2007/10/03)

A variety of 1-amino-alkyl esters and nitriles react with 1,6-dioxo-2,4-diene to give pyrrole derivatives in good yield. Mild basic conditions facilitate the further intramoleular Dieckmann or Thorpe like condensation giving pyrrolizine and indolizine derivatives. These reactions provide simple, two step sequence to pyrrolizine and indolizine derivatives with control of product dictated by the base used for the condensation reaction.
