Calculate Digit Verification of CAS Registry Number 117871-91:
(8*1)+(7*1)+(6*7)+(5*8)+(4*7)+(3*1)+(2*9)+(1*1)=147
147 % 10 = 7

Conversion of some azaheterocyclic-acetic esters and -acetonitriles into fused heterocycles

McKinnon, David M.,Spevack, Perry,Tipples, Graham

, p. 2339 - 2344 (2007/10/02)

Various heterocyclic acid esters and nitriles of the pyridine, thiazole, and imidazole series react with 3-methylthio-4-phenyl-1,2-dithiolium perchlorate to form fused pyridinethiones or dithiolylidene esters.These esters or nitriles also react with trichloromethanesulfenyl chloride to form fused isothiazoles.
