Check Digit Verification of cas no

The CAS Registry Mumber 749216-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,1 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 749216-03:
(8*7)+(7*4)+(6*9)+(5*2)+(4*1)+(3*6)+(2*0)+(1*3)=173
173 % 10 = 3
So 749216-03-3 is a valid CAS Registry Number.

Chemoselective alkylation of 3- and 4-(5-amino-4-hetaryl-2,3-dihydro-3- oxopyrrol-1-yl)benzoic acids

Resnyanskaya,Tverdokhlebov,Volovenko,Shokol

, p. 368 - 371 (2007/10/03)

Alkylation of 3- and 4-(5-amino-4-hetaryl-2,3-dihydro-3-oxopyrrol-1-yl) benzoic acids with phenacyl bromides or chloroacetanilides in DMF in the presence of triethylamine occurs at the carboxy group with high selectivity and yields the corresponding phenacyl and arylcarbamoylmethyl esters. The initial pyrrolylbenzoic acids were synthesized by reaction of 3- and 4-aminobenzoic acids with 4-chloro-2-hetaryl-3-oxo-butyronitriles.
