The CAS Registry Mumber 1349839-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,9,8,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1349839-21:
(9*1)+(8*3)+(7*4)+(6*9)+(5*8)+(4*3)+(3*9)+(2*2)+(1*1)=199
199 % 10 = 9

A one-pot efficient four-component reaction for the synthesis of 2-(arylamino)-2-(5-aryl-1,3,4-oxadiazol-2-yl)propyl benzoate (or acetate) derivatives

Ramazani, Ali,Ahmadi, Yavar,Malekzadeh, Asemeh Mashhadi,Rezaei, Aram

, p. 692 - 698 (2011)

Reactions of (N-isocyanimino) triphenylphosphorane with 2-oxopropylbenzoate (or acetate) in the presence of aromatic carboxylic acids and primary amines proceed smoothly at room temperature and in neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives in high yields. The reaction proceeds smoothly and cleanly under mild conditions, and no side reactions were observed.
