109002-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109002-29-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,0 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109002-29:
(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*2)+(2*2)+(1*9)=81
81 % 10 = 1
So 109002-29-1 is a valid CAS Registry Number.

Phenylation and Dephenylation Reactions: Formation of 1H-Pyrazoloquinoxalines
Pillai, P. Madhavan,Ramabhadran, P.
, p. 901 - 904 (2007/10/02)
1,3-Diphenyl-1H-pyrazoloquinoxaline (9) has been isolated as a byproduct in the conversion of quinoxaline-2-carboxaldehyde phenylhydrazone (1) into 1-phenyl-1H-pyrazoloquinoxaline (5) using stored phenylhydrazine as the dehydrogenating agent
