Check Digit Verification of cas no

The CAS Registry Mumber 72795-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,9 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72795-81:
(7*7)+(6*2)+(5*7)+(4*9)+(3*5)+(2*8)+(1*1)=164
164 % 10 = 4
So 72795-81-4 is a valid CAS Registry Number.

Synthesis and nucleophilic properties of 1,2 -dialkyl-3-nitropyrroles and 1,5-dialkyl-4-nitropyrrole-2-carboxylic acid derivatives

Molins-Pujol, Antoni M.,Moranta, Concepcio,Arroyo, Carmina,Rodriguez, M. Teresa,Meca, M. Carmen,Pujol, M. Dolors,Bonal, Joaquim

, p. 2277 - 2289 (1996)

1,2-Dialkyl-3-nitropyrroles 1 are versatile synthetic tools for obtaining substituted pyrrolidines or fused ring heterocycles such as pyrrolopyridines, pyrrolopyrimidines or pyrroloazepines. We have established a method for obtaining compounds related to structure 1 and studied the reactivity as a nucleophile of the benzylic type moiety in the alkyl residue bound to position 2.
