72277-16-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72277-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,7 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72277-16:
(7*7)+(6*2)+(5*2)+(4*7)+(3*7)+(2*1)+(1*6)=128
128 % 10 = 8
So 72277-16-8 is a valid CAS Registry Number.

Method To Prepare beta-Functionalized Aliphatic Esters

-

Paragraph 0021; 0022; 0023; 0024, (2013/09/12)

The invention pertains to a new route to prepare β-functionalized carboxylic acid esters in a one-pot reaction, by reacting an olefinic acid ester in the presence of a catalyst system, comprising a Rh(I)-complex, together with an aryl boron or a diamine a

Potassium trifluoro(organo)borates in rhodium-catalyzed 1,4-additions to α,β-unsaturated esters

Navarre, Laure,Pucheault, Mathieu,Darses, Sylvain,Genet, Jean-Pierre

, p. 4247 - 4250 (2007/10/03)

This letter describes an efficient and enantioselective conjugate addition of highly stable potassium trifluoro(organo)borates to α,β- unsaturated esters. This reaction, catalyzed by chiral rhodium(I) complexes, affords Michael adducts with high yields an
