Calculate Digit Verification of CAS Registry Number 947393-91:
(8*9)+(7*4)+(6*7)+(5*3)+(4*9)+(3*3)+(2*9)+(1*1)=221
221 % 10 = 1
So 947393-91-1 is a valid CAS Registry Number.

Synthesis and antibaterial activities of bis[(3-benzyloxypheny1)-1,2,4- triazolo[3,4-b]-[1,3,4]thiadiazole derivatives

Hu, Lang-Xi,Li, De-Jiang

, p. 73 - 77 (2011/06/24)

Bis[(3-benzyloxyphenyl)-1,2,4-triazolo[3,4-b]-[1,3,4]thiadiazole derivatives 3 were synthesized in high yields by reaction of 3-benzyloxyphenyl-4-amino-5-mercapto-1,2,4-triazole 1 with dicarboxylic acid 2 in the presence of POCl3 and tetrabutylammonium iodide as catalyst. The preliminary antibacterial tests showed that most of them were effective against S. aureus, E.coli and B.subtilis.
