Check Digit Verification of cas no

The CAS Registry Mumber 181480-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,4,8 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 181480-92:
(8*1)+(7*8)+(6*1)+(5*4)+(4*8)+(3*0)+(2*9)+(1*2)=142
142 % 10 = 2
So 181480-92-2 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 (1997)

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.
