Check Digit Verification of cas no

The CAS Registry Mumber 130821-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,2 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130821-77:
(8*1)+(7*3)+(6*0)+(5*8)+(4*2)+(3*1)+(2*7)+(1*7)=101
101 % 10 = 1
So 130821-77-1 is a valid CAS Registry Number.

Tridentate nitrogen phosphine ligand containing arylamine NH as well as preparation method and application thereof

-

Paragraph 0095-0102; 0105-0109, (2021/06/26)

The invention discloses a tridentate nitrogen phosphine ligand containing arylamine NH as well as a preparation method and application thereof, and belongs to the technical field of organic synthesis. The tridentate nitrogen phosphine ligand disclosed by the invention is the first case of tridentate nitrogen phosphine ligand containing not only a quinoline amine structure but also chiral ferrocene at present, a noble metal complex of the type of ligand shows good selectivity and extremely high catalytic activity in an asymmetric hydrogenation reaction, meanwhile, a cheap metal complex of the ligand can also show good selectivity and catalytic activity in the asymmetric hydrogenation reaction, and is very easy to modify in the aspects of electronic effect and space structure, so that the ligand has huge potential application value. A catalyst formed by the ligand and a transition metal complex can be used for catalyzing various reactions, can be used for synthesizing various drugs, and has important industrial application value.
