Check Digit Verification of cas no

The CAS Registry Mumber 121071-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,7 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121071-89:
(8*1)+(7*2)+(6*1)+(5*0)+(4*7)+(3*1)+(2*8)+(1*9)=84
84 % 10 = 4
So 121071-89-4 is a valid CAS Registry Number.

DIASTEREOSELECTIVITY IN THE TiCl4-MEDIATED ALDOL REACTION OF CYCLIC DIENYLSILYL ETHERS

Barner, Bruce A.,Liu, Yalei,Rahman, Md. Abdur

, p. 6101 - 6112 (2007/10/02)

Cyclic dienylsilyl ethers derived from α,β-unsaturated ketones undergo TiCl4-catalyzed crossed aldol reactions with aldehydes, giving β'-hydroxy enone systems with good diastereoselectivity in most cases.The direction of stereocontrol (syn versus anti) in
