66751-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66751-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,7,5 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66751-95:
(7*6)+(6*6)+(5*7)+(4*5)+(3*1)+(2*9)+(1*5)=159
159 % 10 = 9
So 66751-95-9 is a valid CAS Registry Number.

A Novel Ring Closure to Furoquinoxaline
Amer, Adel,Ventura, Montserrat,Zimmer, Hans
, p. 992 - 996 (2007/10/02)
An efficient method for the synthesis of furoquinoxalines has been devised.Thus, 3-halo-2-arylfuroquinoxalines, 5a-5c were synthesized by the action of conc.H2SO4 on 3-(1-halo-2-oxo-2-arylethyl)-2(1H)quinoxalinones, 3b, 3c and 3f respectivel
