5097-45-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5097-45-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,9 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5097-45:
(6*5)+(5*0)+(4*9)+(3*7)+(2*4)+(1*5)=100
100 % 10 = 0
So 5097-45-0 is a valid CAS Registry Number.

Strunskaya,Bredikhina,Azancheev,Bredikhin
, p. 1330 - 1334 (2007/10/03)
3-Aryloxy-1,2,5-thiadiazoles were synthesized by the Ullmann reaction either from 3-chloro-1,2,5-thiadiazoles and phenols having donor substituents or from 3-hydroxy-1,2,5-thiadiazoles and chlorobenzenes containing acceptor substituents.
