54020-52-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54020-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54020-52:
(7*5)+(6*4)+(5*0)+(4*2)+(3*0)+(2*5)+(1*2)=79
79 % 10 = 9
So 54020-52-9 is a valid CAS Registry Number.

Enantio- and Diastereoselective Catalysis of Addition Reaction of Allylic Silanes and Stannanes to Glyoxylates by Binaphthol-derived Titanium Complex

Aoki, Seiichi,Mikami, Koichi,Terada, Masahiro,Nakai, Takeshi

, p. 1783 - 1792 (1993)

Chiral titanium complex (1), prepared in situ from optically pure binaphthol and diisopropoxytitanium dihalide in the presence of molecular sieves, is shown to catalyze the addition reactions of crotylsilanes and -stannanes to glyoxylates to afford (syn)-α-hydroxy-β-methyl esters in highly scalemic forms with high diastereoselectivity.Key Words: Asymmetric catalysis; Enantiocontrol; Diastereocontrol; Allylic silane; Allylic stannane; Carbonyl-addition reaction; Carbonyl-enereaction; Glyoxylate; Binaphthol-derived titanium dihalide; Chiral titanium complex
