325793-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 325793-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,5,7,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 325793-45:
(8*3)+(7*2)+(6*5)+(5*7)+(4*9)+(3*3)+(2*4)+(1*5)=161
161 % 10 = 1
So 325793-45-1 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of new 2-phenylethynylbenzothiazoles and related salts
Magdolen,Zahradnik,Foltinova
, p. 1023 - 1027 (2007/10/03)
New 2-phenylethynylbenzothiazoles were synthesized by coupling reaction between 2-iodobenzothiazole and substituted phenylacetylenes under palladium catalysis. The modified Wittig reaction was used to prepare the substituted phenylacetylenes from correspo
