128900-19-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128900-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128900-19:
(8*1)+(7*2)+(6*8)+(5*9)+(4*0)+(3*0)+(2*1)+(1*9)=126
126 % 10 = 6
So 128900-19-6 is a valid CAS Registry Number.

New Supported β-Amino Alcohols as Efficient Catalysts for the Enantioselective Addition of Diethylzinc to Benzaldehyde under Flow Conditions

Burguete, M. Isabel,Garcia-Verdugo, Eduardo,Vicent, Maria J.,Luis, Santiago V.,Pennemann, Helmut,Graf Von Keyserling, Nikolai,Martens, Jurgen

, p. 3947 - 3950 (2007/10/03)

(Matrix Presented) Polymeric monoliths 10 containing an amino alcohol moiety derived from an industrial waste material represent one of the best ligands for the enantioselective catalytic addition of ZnEt2 to benzaldehyde (99% ee), being recove

Chemical differentiation of enantiotopic groups: Diastereoselective opening of a prochiral dilactone

Deseke, Eckart,Hoyer, Wolfgang,Winterfeldt, Ekkehard

, p. 14577 - 14598 (2007/10/03)

Prochiral dilactone 1 has been synthesized and subjected to diastereoselective nucleophilic opening. The structural features of chiral, enantiomerically pure nucleophiles have been optimized regarding their capability to perform prochiral recognition at dilactone 1. 3-Ketoglutaric mono acid products 2 of dilactone opening, which are versatile building blocks for natural product synthesis, have been obtained in diastereomeric ratios up to 84:16 and were enriched by subsequent crystallization to 97.5:2.5.

Utilization of Industrial Waste Materials, 1. - Synthesis of New Primary and Secondary Chiral 1,2-Diamines

Stingl, Klaus,Martens, Juergen

, p. 243 - 250 (2007/10/02)

Primary and secondary 1,2-diamines with three or four stereogenic centers were synthesized starting from the benzyl ester of the bicyclic proline analogue (all-R)-2-azabicyclooctane-3-carboxylic acid by a four- or five-step procedure.This is an example for the utilization of the industrial waste material (all-R)-2b. - Key Words: 1,2-Diamines / 2-Azabicyclooctanes / Proline analogue / Cyclopentapyrroles

TANDEM GENERATION AND INTRAMOLECULAR TRAPPING OF CHIRAL STABILISED AZOMETHINE YLIDS WITH ALKYNE DIPOLAROPHILES

Harwood, Laurence M.,Kitchen, Lara C.

, p. 6603 - 6606 (2007/10/02)

Due to steric contraints imposed upon the bridging chain by the three-carbon linear unit associated with the alkyne, hex-5-ynal condenses with (5R)-phenylmorpholin-2-one (1) and undergoes intramolecular 3+2 dipolar cycloaddition via the syn-azomethine yli
