Check Digit Verification of cas no

The CAS Registry Mumber 131929-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131929-40:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*9)+(2*4)+(1*0)=123
123 % 10 = 3
So 131929-40-3 is a valid CAS Registry Number.

Diastereofacial Selection in Titanium Tetrachloride-Promoted Aldol Reactions with the Silyl Ketene Acetal of Methyl (R)-3-Hydroxybutanoate

Shirai, Fumiyuki,Gu, Jin-Hua,Nakai, Takeshi

, p. 1931 - 1934 (2007/10/02)

The title reaction is shown to exhibit a high level of "anti" diastereofacial selection, in contrast to the "syn" selection observed for the reaction with the dilithium enolate of the chiral ester.Mechanistic grounds for the "anti" stereoselection are dis
