Check Digit Verification of cas no

The CAS Registry Mumber 1207722-36-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,7,2 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1207722-36:
(9*1)+(8*2)+(7*0)+(6*7)+(5*7)+(4*2)+(3*2)+(2*3)+(1*6)=128
128 % 10 = 8
So 1207722-36-8 is a valid CAS Registry Number.

NHC (N-heterocyclic carbene) ligand, ruthenium catalyst thereof, preparation methods and application

-

Paragraph 0162; 0166-0168, (2019/08/02)

The invention relates to an NHC (N-heterocyclic carbene) ligand, a ruthenium catalyst thereof, preparation methods and an application of the catalyst. The NHC ligand structures are shown in formulas Ia and Ib respectively, and the corresponding ruthenium catalyst structures are shown in formulas IIa and IIb respectively. After large steric hindrance and electron-rich groups are simultaneously introduced to the NHC ligand structures, the catalytic activity and the stability of the ruthenium complex catalyst of the NHC ligand are notably improved, and the application range of the ruthenium complex catalyst of the NHC ligand is notably enlarged.
