Check Digit Verification of cas no

The CAS Registry Mumber 497963-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,9,6 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 497963-50:
(8*4)+(7*9)+(6*7)+(5*9)+(4*6)+(3*3)+(2*5)+(1*0)=225
225 % 10 = 5
So 497963-50-5 is a valid CAS Registry Number.

A new methodology of annelation of five- and seven-membered heterocycles to quinoxalines

Boguslavskiy,Ponizovskiy,Kodess,Charushin

, p. 2175 - 2184 (2003)

Pyrazolo[3,4-b]-, isoxazolo[4,5-b]-, benzo[2,3]-1,4-diazepino-, and benzo[2,3]-1-4-oxazepinoquinoxalines were prepared by reactions of 2-quinoxalinecarboxaldehyde with 1,2-N,N-, 1,2-N,O and 1,4-N,N- and 1,4-N,O-dinucleophiles.

Synthesis of fused quinoxalines

Ponizovsky, Michail G.,Boguslavsky, Artem M.,Kodess, Mikhail I.,Charushin, Valery N.,Chupakhin, Oleg N.

, p. 68 - 70 (2007/10/03)

The intramolecular cyclization of NH and N-alkyl quaternary salts of 2-quinoxaline-2-carboxaldehyde hydrazones affords pyrazolo-[3,4-b]quinoxalines in good yields.
