73698-08-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73698-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,9 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73698-08:
(7*7)+(6*3)+(5*6)+(4*9)+(3*8)+(2*0)+(1*8)=165
165 % 10 = 5
So 73698-08-5 is a valid CAS Registry Number.

Rhodium-catalyzed, highly enantioselective 1,2-addition of aryl boronic acids to α-ketoesters and α-diketones using simple, chiral sulfur-olefin ligands

Zhu, Ting-Shun,Jin, Shen-Shuang,Xu, Ming-Hua

supporting information; experimental part, p. 780 - 783 (2012/02/06)

Simply the best: The title reaction has been achieved by asymmetric rhodium catalysis employing an extremely simple, chiral N-(sulfinyl)cinnamylamine ligand. A variety of highly enantioenriched, tertiary α-hydroxy carbonyl derivatives were easily accessed

Asymmetric Addition of Organometallics to Chiral Ketooxazolines. Preparation of Enantiomerically Enriched α-Hydroxy Acids

Meyers, A. I.,Slade, Joel

, p. 2785 - 2791 (2007/10/02)

Addition of Grignard and organolithium reagents to chiral α-ketooxazolines results in α-substituted α-hydroxyoxazoline derivatives which on hydrolytic removal of the chiral auxiliary groups give rise to α-substituted α-hydroxy acids in 30-87 percent enantiomeric excess (ee).Studies on the various parameters (solvents, temperature, substituents) were undertaken to reach optimum asymmetric induction.
