20264-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20264-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20264-78:
(7*2)+(6*0)+(5*2)+(4*6)+(3*4)+(2*7)+(1*8)=82
82 % 10 = 2
So 20264-78-2 is a valid CAS Registry Number.

Heterocycles. 3. Synthesis and Spectral Data of Some 2-Pyrazolines
El-Rayyes, Nizar R.,Hovakeemian, George H.,Hmoud, Hayat S.
, p. 225 - 229 (2007/10/02)
The reaction of 1,3-diaryl-2-propen-1-ones (Ia-o) with hydrazine and methyl- and phenylhydrazine produced different substituted 2-pyrazolines (III).The structures of these products were evident from their chemical and spectroscopic analysis.
