140147-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140147-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,4 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140147-59:
(8*1)+(7*4)+(6*0)+(5*1)+(4*4)+(3*7)+(2*5)+(1*9)=97
97 % 10 = 7
So 140147-59-7 is a valid CAS Registry Number.

Stereoselective Aldol Reactions. Reaction of Chiral Ester Titanium Enolate with Aldehydes
Xiang, YiBin,Olivier , Eric,Ouimet, Nathalie
, p. 457 - 460 (2007/10/02)
The chiral ester 1 was enolized under TiCl4/Et3N conditions and reacted with aldehydes to give moderate to good stereoselectivities.The chiral auxiliary group can be removed by simple saponification and recovered.
