87853-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87853-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,5 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87853-05:
(7*8)+(6*7)+(5*8)+(4*5)+(3*3)+(2*0)+(1*5)=172
172 % 10 = 2
So 87853-05-2 is a valid CAS Registry Number.

KETONE-KETONE CONDENSATIONS INVOLVING MESITYL OXIDE
Sosnovskikh, V. Ya.,Ovsyannikov, I. S.
, p. 1924 - 1929 (2007/10/02)
The mixed condensation of mesityl oxide with alkyl phenyl and aryl phenyl ketones was realized in the presence of N-ethylanilinomagnesium bromide, and a series of α,β-unsaturated β-ketols was obtained.It was shown that the dehydratation of the ketols, syn
