134426-16-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134426-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,2 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134426-16:
(8*1)+(7*3)+(6*4)+(5*4)+(4*2)+(3*6)+(2*1)+(1*6)=107
107 % 10 = 7
So 134426-16-7 is a valid CAS Registry Number.

Synthesis and Reactions of 2-Arylhydrazono-2-cyano-N,N-dialkylacetamidines
Schaefer, H.,Gewald, K.,Bellmann, P.,Gruner, M.
, p. 195 - 207 (2007/10/02)
The title compounds 3 were synthesized by reaction of arylhydrazono-malononitriles 1 with secondary amines and used for subsequent cyclization reactions.Thus, 3 undergoes cyclooxidation by treatment with CuSO4/pyridine to form the 5-dialkylamino-2-aryl-1,
