75470-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75470-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 75470-76:
(7*7)+(6*5)+(5*4)+(4*7)+(3*0)+(2*7)+(1*6)=147
147 % 10 = 7
So 75470-76-7 is a valid CAS Registry Number.

Synthesis of thieno[2,3-b]quinoxalines from 2-haloquinoxalines
Armengol, Montserrat,Joule, John A.
, p. 154 - 158 (2007/10/03)
Thieno[2,3-b]quinoxalines were synthesized from 2-haloquinoxalines using palladium catalyst. The coupling of latter with alkynes and addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced was described. The resulting dibromid
