Check Digit Verification of cas no

The CAS Registry Mumber 138222-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,2 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138222-93:
(8*1)+(7*3)+(6*8)+(5*2)+(4*2)+(3*2)+(2*9)+(1*3)=122
122 % 10 = 2
So 138222-93-2 is a valid CAS Registry Number.

Study of the Mannich reaction: β-amino-methylation of N-aryl and N-azaheteroaryl-substituted 2,5-dimethylpyrroles, compounds with potential biological activity

, p. 431 - 438 (2007/10/02)

Owing to the increasing need of drugs for the treatment of a variety of fungal and bacterial opportunistic infections, a study has been started with the aim of synthesizing structures amenable to a number of easy-to-perform structural modifications in order to meet the requirement of bypassing resistance phenomena. This paper reports on the synthesis of several N-(α-azaheteroaryl)-substituted 2,5-dimethyl-pyrroles bearing in one β-position (or in both β-positions) aminomethyl groups, introduced via a Mannich reaction. Electronic and steric effects by the N-(azaheteroaryl) substituents and the 2- and 5-methyl groups on the course of the Mannich reaction are discussed along with the results of in vitro tests against many Candida species, some bacteria, and several pathogenic plant fungi.
