243665-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 243665-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,6,6 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 243665-72:
(8*2)+(7*4)+(6*3)+(5*6)+(4*6)+(3*5)+(2*7)+(1*2)=147
147 % 10 = 7
So 243665-72-7 is a valid CAS Registry Number.

, p. 390 - 393 (2007/10/03)
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
