Check Digit Verification of cas no

The CAS Registry Mumber 22031-15-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,3 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22031-15:
(7*2)+(6*2)+(5*0)+(4*3)+(3*1)+(2*1)+(1*5)=48
48 % 10 = 8
So 22031-15-8 is a valid CAS Registry Number.

Homogeneous Catalytic Hydrogenation of CO2 to Methanol – Improvements with Tailored Ligands

Scharnagl, Florian Korbinian,Hertrich, Maximilian Franz,Neitzel, Gordon,Jackstell, Ralf,Beller, Matthias

, p. 374 - 379 (2019/01/04)

Improved molecularly-defined cobalt catalysts for the hydrogenation of carbon dioxide to methanol have been developed. A key factor for increased productivity (up to twofold compared to previous state-of-the-art-system) is the specific nature of substitue

Triphos derivatives and diphosphines as ligands in the ruthenium-catalysed alcohol amination with NH3

Nakagawa,Derrah,Schelwies,Rominger,Trapp,Schaub

, p. 6856 - 6865 (2016/05/19)

The ruthenium-triphos and diphosphine-catalysed amination of alcohols with ammonia is reported. Various types of triphos derivatives with electron-donating functional group were synthesized and used as ligands in the Ru-catalysed alcohol amination with NH3. The triphos derivatives are effective for the formation of primary amines. On the other hand, if hemilabile diphosphines as tridentate ligands are used, mixtures of secondary-along with primary amines are obtained. It was found that even simple diphosphines can be used as ligands for the selective formation of the secondary amines. The diphosphine system allows a new entry to the Ru-catalysed formation of secondary amines.

Eine einfache Synthese von Tripod-Liganden H3CC(CH2PAr2)3: Anwendungsbreite und Komplexchemie
