1164520-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1164520-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,4,5,2 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1164520-79:
(9*1)+(8*1)+(7*6)+(6*4)+(5*5)+(4*2)+(3*0)+(2*7)+(1*9)=139
139 % 10 = 9
So 1164520-79-9 is a valid CAS Registry Number.

5-Acyl-2-aryl-4-methyl thiazoles 1 have been converted to 1-(2'-aryl- 4'-methylthiazol-5'-yl)-3-aryl-2-propen-1-ones 2 by Claisen-Schmidt condensation. The chalcones 2 are brominated to give their bromo derivatives 3 which on hydrolysis yield 1-(2'-aryl-4
