Check Digit Verification of cas no

The CAS Registry Mumber 335239-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,5,2,3 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 335239-64:
(8*3)+(7*3)+(6*5)+(5*2)+(4*3)+(3*9)+(2*6)+(1*4)=140
140 % 10 = 0
So 335239-64-0 is a valid CAS Registry Number.

Highly regio- and stereo-selective alkyl substitution with copper reagents for the construction of chiral trifluoromethylated quaternary carbon centres

Hiraoka, Shuichi,Yamazaki, Takashi,Kitazume, Tomoya

, p. 1497 - 1498 (2007/10/03)

A new route for the asymmetric construction of quaternary carbon centres containing a trifluoromethyl group has been established using a highly regio- and stereo-selective SN2′ reaction of organocopper and organocuprate reagents with allylic mesylates 4 and 8.
