Check Digit Verification of cas no

The CAS Registry Mumber 190775-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,7 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 190775-71:
(8*1)+(7*9)+(6*0)+(5*7)+(4*7)+(3*5)+(2*7)+(1*1)=164
164 % 10 = 4
So 190775-71-4 is a valid CAS Registry Number.

Design and synthesis of C3-symmetric molecules containing oxepine and benzofuran moieties via Metathesis

Gupta, Naveen Kumar,Kotha, Sambasivarao,Solanke, Balaji. U.

, (2021/07/17)

We report a new synthetic strategy to C3-symmetric star-shaped phenyl and triazine central cores bearing oxepine and benzofuran ring systems. In this regard, we have explored the application of metathetic strategy to construct C3-sym

Anti-Markovnikov Hydroheteroarylation of Unactivated Alkenes with Indoles, Pyrroles, Benzofurans, and Furans Catalyzed by a Nickel-N-Heterocyclic Carbene System

Schramm, York,Takeuchi, Makoto,Semba, Kazuhiko,Nakao, Yoshiaki,Hartwig, John F.

supporting information, p. 12215 - 12218 (2015/10/12)

We report the catalytic addition of C-H bonds at the C2 position of heteroarenes, including pyrroles, indoles, benzofurans, and furans, to unactivated terminal and internal alkenes. The reaction is catalyzed by a combination of Ni(COD)2 and a sterically hindered, electron-rich N-heterocyclic carbene ligand or its analogous Ni(NHC)(arene) complex. The reaction is highly selective for anti-Markovnikov addition to α-olefins, as well as for the formation of linear alkylheteroarenes from internal alkenes. The reaction occurs with substrates containing ketones, esters, amides, boronate esters, silyl ethers, sulfonamides, acetals, and free amines.
