149242-65-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149242-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,4 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 149242-65:
(8*1)+(7*4)+(6*9)+(5*2)+(4*4)+(3*2)+(2*6)+(1*5)=139
139 % 10 = 9
So 149242-65-9 is a valid CAS Registry Number.

Kinetic resolution of quaternary and tertiary ss-hydroxy esters

Schipper, Derek J.,Rousseaux, Sophie,Fagnou, Keith

scheme or table, p. 8343 - 8347 (2010/02/28)

Selectivity factors: The resolution of tertiary and secondary alcohols, which arise from ketone and aldehyde aldol additions, proceeds in the presence of (1S, 2R)-N-methylephedrine (see example). The method is technically simple, easily scalable, and prov

The E/Z geometry of the enolate component determines face selection of the aldehyde component in chiral diazaborolidine-directed enantioselective aldol coupling

Corey,Lee

, p. 1737 - 1740 (2007/10/02)

An analysis of the effect of enolate geometry on transition-state energy explains the stereochemistry of aldol reactions of acetate and propionate esters with aldehydes using as reagent the chiral diazaborolidine 1.
