Check Digit Verification of cas no
The CAS Registry Mumber 102769-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102769-76:
(8*1)+(7*0)+(6*2)+(5*7)+(4*6)+(3*9)+(2*7)+(1*6)=126
126 % 10 = 6
So 102769-76-6 is a valid CAS Registry Number.

Oxidative Coupling of 5-Aminopyrazoles with p-Phenylenediamines
Hennig, L.,Hofmann, J.,Wilde, H.,Mann, G.
, p. 342 - 348 (2007/10/02)
By oxidative coupling of 5-amino-3-methyl-1-phenyl-pyrazole 4 with N,N-diethyl-p-phenylenediamine the 4-(4-N,N-diethylamino-phenylimino)-3-methyl-1-phenyl-2-pyrazolin-5-imin 5 is formed. 5 is oxidized very easily to the 1H-pyrazoloquinoxaline 6a.Th
