156994-73-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156994-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,9 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156994-73:
(8*1)+(7*5)+(6*6)+(5*9)+(4*9)+(3*4)+(2*7)+(1*3)=189
189 % 10 = 9
So 156994-73-9 is a valid CAS Registry Number.

Asymmetric synthesis of ketoprofen: a surprising base catalyst effect during asymmetric addition of pantolactone to methyl (3-benzoylphenyl) ketene

Calmes, Monique,Daunis, Jacques,Jacquier, Robert,Natt, Francois

, p. 6875 - 6880 (1994)

The best diastereoselectivity of addition of a chiral alcohol to the ketene derived from ketoprofen was obtained with R or S pantolactone (ed=99percent).Depending on the tertiary amine used both for ketene formation and as catalyst during addition, the diastereoisomeric ratio of esters could be strongly modified and even inverted.Mild saponification afforded R or S ketoprofen in enantiomeric excess of up to 99percent.
