Check Digit Verification of cas no

The CAS Registry Mumber 79205-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,0 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79205-14:
(7*7)+(6*9)+(5*2)+(4*0)+(3*5)+(2*1)+(1*4)=134
134 % 10 = 4
So 79205-14-4 is a valid CAS Registry Number.

Pyoluteorin Derivatives. II. Synthetic Approaches to Pyrrole Ring Substituted Pyoluteorins (1)

Cue, Berkeley W.,Chamberlain, Nancy

, p. 667 - 670 (2007/10/02)

A method for the regiospecific synthesis of 3-substituted 2-aroylpyrroles is described.These pyrroles, which are structurally related to the naturally occuring antibiotic pyoluteorin, are prepared by a Friedel-Crafts aroylation of 4-substituted pyrrole-3-carboxylic acid esters with 2,6-dimethoxybenzoyl chloride.The carboalkoxy group is then removed by hydrolysis and decarboxylation to produce isomerically pure 3-substituted-2-(2',6'-dimethoxybenzoyl)pyrroles (5 and 13).Conversion of these pyrroles into pyoluteorin-like coumpounds led to some unexpected products which arise from facile cleavage of the dihydroxybenzoyl portion of the molecules during chlorination.
