333452-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 333452-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,4,5 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 333452-38:
(8*3)+(7*3)+(6*3)+(5*4)+(4*5)+(3*2)+(2*3)+(1*8)=123
123 % 10 = 3
So 333452-38-3 is a valid CAS Registry Number.

Nucleophilic substitutions in 6,7-difluoroquinoxalines
Charushin,Mokrushina,Tkachev
, p. 71 - 80 (2007/10/03)
The reactions of 6,7-difluoroquinoxalines with a number of nucleophiles, such as cycloalkylimines, hydrazine, sodium hydroxide and alkoxides have been shown to result in substitution of either one or two fluoro atoms depending on the nature of nucleophiles.
