159951-54-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 159951-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,5 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 159951-54:
(8*1)+(7*5)+(6*9)+(5*9)+(4*5)+(3*1)+(2*5)+(1*4)=179
179 % 10 = 9
So 159951-54-9 is a valid CAS Registry Number.

Catalytic, Enantioselective, Inverse Electron-Demand Diels-Alder (IEDDA) Reactions of 3-Carbomethoxy-2-Pyrone (3-CMP)

Marko, Istvan E,Evans, Graham R

, p. 2771 - 2774 (1994)

Cycloaddition reactions between 3-CMP 1 and various vinyl ethers and vinyl sulphides, catalysed by the Yb(OTf)-Binol complex, afford bicyclic lactones 3 in moderate to exellent enantiomeric excesses.

Remarkable effect of basics ligands in the lanthanide-catalysed enantioselective cycloadditions of 3-carbomethoxy-2-pyrone (3-CMP)

Marko, Istvan E.,Chelle-Regnaut, Isabelle,Leroy, Bernard,Warriner, Stuart L.

, p. 4269 - 4272 (2007/10/03)

The key-role of basic ligands in attaining high enantiomeric excess in the lanthanide catalysed asymmetric cycloadditions of 3-CMP is reported. A model, rationalising all our previous observations is discussed.

Marko, Istvan E.,Evans, Graham R.,Declercq, Jean-Paul,Feneau-Dupont, Janine,Tinant, Bernard

, p. 295 - 298 (2007/10/02)

When catalysed by the Kobayashi : Yb(OTf)3-Binol complex, vinyl ethers and vinyl sulphides undergo highly enantioselective IEDDA reactions with 3-carbomethoxy-2-pyrone.
