Check Digit Verification of cas no

The CAS Registry Mumber 678150-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 678150-52:
(8*6)+(7*7)+(6*8)+(5*1)+(4*5)+(3*0)+(2*5)+(1*2)=182
182 % 10 = 2
So 678150-52-2 is a valid CAS Registry Number.

Highly enantioenriched homoenolate reagents by asymmetric γ-deprotonation of achiral 1-silyl-substituted 1-alkenyl carbamates

Reuber, Jenny,Froehlich, Roland,Hoppe, Dieter

, p. 783 - 786 (2004)

1-Trimethylsilyl-1-alkenyl carbamates 1 are deprotonated by n-butyllithium/(-)-sparteine (2) with a high degree of enantiotopic differentiation in the γ-position to form the enantiomerically enriched allyllithium derivatives 3. Trapping these with several
