Check Digit Verification of cas no

The CAS Registry Mumber 183268-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,2,6 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 183268-75:
(8*1)+(7*8)+(6*3)+(5*2)+(4*6)+(3*8)+(2*7)+(1*5)=159
159 % 10 = 9
So 183268-75-9 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 (2007/10/03)

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.
