86251-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86251-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,5 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86251-40:
(7*8)+(6*6)+(5*2)+(4*5)+(3*1)+(2*4)+(1*0)=133
133 % 10 = 3
So 86251-40-3 is a valid CAS Registry Number.

Oxidation of Bis-arylhydrazones of 3,3-Dimethylpentane-2,4-dione With Silver Oxide
Stephanidou-Stephanatou, J.
, p. 431 - 434 (2007/10/02)
Oxidation of the title bis-arylhydrazones 2 with silver oxide gives 1-aryl-5-arylazo-3,4,4,5-tetramethyl-2-pyrazolines 4 in almost quantitative yield.The spectral data of the pyrazolines 4 as well as the reaction mechanism are discussed.
