Check Digit Verification of cas no

The CAS Registry Mumber 1219359-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,3,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1219359-99:
(9*1)+(8*2)+(7*1)+(6*9)+(5*3)+(4*5)+(3*9)+(2*9)+(1*9)=175
175 % 10 = 5
So 1219359-99-5 is a valid CAS Registry Number.

Synthesis, characterization and antimicrobial evaluation of some arylidenehy drazon of uropyrimidines and thienopyrimidines

Hossain Bhuiyan, Md. Mosharef,Rahman, Khandker M. M.,Islam, Md. Imjamul

experimental part, p. 180 - 185 (2010/07/05)

Cyclization of hetcroaromatic o-aminoestcr with formamide afforded furo[2, 3-d]pyrimidin-4(3II)-one which was then chlorinated with thionyl chloride followed by displacement by hydrazine hydrate to furnish hydrazinofuro [2, 3-d]pyrimidine. Reaction of hydrazino derivative with formic acid gave furo[3, 2-c][ 1, 2, 4]triazolo[4, 3-c]pyrimidine. Treatment of hydrazino derivative with aromatic aldehydes afforded arylidenehydrazonofuro[2, 3-d]pyrimidine derivatives. Reaction of o-aminonitrile with carbon disulphide, followed by methylation with methyl iodide and subsequent reaction with hydrazine hydrate afforded hydrazinothieno[2, 3-d]pyrimidine. 14 derivatives were synthesized. Some of these derivatives exhibited pronounced antimicrobial activities against S. typhi, S. aureus, S. dysenteriae, V. cholerae, C. lunata, A. alternata, C. corchori, F. equeseti and M. phaseolina.
