Check Digit Verification of cas no

The CAS Registry Mumber 219666-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,6 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 219666-96:
(8*2)+(7*1)+(6*9)+(5*6)+(4*6)+(3*6)+(2*9)+(1*6)=173
173 % 10 = 3
So 219666-96-3 is a valid CAS Registry Number.

Intramolecular cycloadditions of nittones derived from 1-allyl-2- pyrrolecarbaldehyde as a route to racemic and enantiopure pyrrolizidines and indolizidines

Arnone, Alberto,Broggini, Gianluigi,Passarella, Daniele,Terraneo, Alberto,Zecchi, Gaetano

, p. 9279 - 9284 (2007/10/03)

A version of the intramolecular nitrone cycloaddition strategy, using 2- pyrrolecarbaldehyde as starting material, has been developed to synthesize new pyrrolizidines and indolizidines structurally related to biologically active alkaloids. The target molecules have been accessible in racemic as well as enantiopure form.
