Check Digit Verification of cas no

The CAS Registry Mumber 142779-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,7 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142779-27:
(8*1)+(7*4)+(6*2)+(5*7)+(4*7)+(3*9)+(2*2)+(1*7)=149
149 % 10 = 9
So 142779-27-9 is a valid CAS Registry Number.

Dramatic reversal of enantioselectivity in β-aminoalcohol-catalyzed addition of diethylzinc to aldehydes

Kimura,Sugiyama,Ishizuka,Kunieda

, p. 3147 - 3150 (1992)

β-Aminoalcohols sterically constrained by a dibenzobicyclo[2.2.2] ring system serve well as chiral catalysts in highly enantioselective additions of diethylzinc to aldehydes (up to 98% e.e.). A dramatic reversal of the enantioselectivity is observed when
