Check Digit Verification of cas no

The CAS Registry Mumber 221469-82-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,4,6 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 221469-82:
(8*2)+(7*2)+(6*1)+(5*4)+(4*6)+(3*9)+(2*8)+(1*2)=125
125 % 10 = 5
So 221469-82-5 is a valid CAS Registry Number.

A Novel Synthesis of Highly Branched-Alkyl Aryl Ketones Using the Conjugate Addition of the Gilman Lithio Cuprate to β-Methylthio-α,β-unsaturated Ketones: Abnormal Reactivity of the Intermediary Enolates toward Molecular Oxygen

Arai, Takayuki,Akazome, Motohiro,Ogura, Katsuyuki

, p. 107 - 108 (2007/10/03)

In order to synthesize highly branched-alkyl aryl ketones, 1-(methylthio)-1-alken-2-yl phenyl ketones were subjected to the reaction with lithium dialkylcuprate. The high reactivity of an intermediary enolate toward molecular oxygen was found to give α-hy
