Check Digit Verification of cas no

The CAS Registry Mumber 1201189-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,1,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1201189-40:
(9*1)+(8*2)+(7*0)+(6*1)+(5*1)+(4*8)+(3*9)+(2*4)+(1*0)=103
103 % 10 = 3
So 1201189-40-3 is a valid CAS Registry Number.

Organophosphorus-catalyzed relay oxidation of H-Bpin: electrophilic C-H borylation of heteroarenes

Lipshultz, Jeffrey M.,Fu, Yue,Liu, Peng,Radosevich, Alexander T.

, p. 1031 - 1037 (2021/02/06)

A nontrigonal phosphorus triamide (1, P{N[o-NMe-C6H4]2}) is shown to catalyze C-H borylation of electron-rich heteroarenes with pinacolborane (HBpin) in the presence of a mild chloroalkane reagent. C-H borylation proceeds for a range of electron-rich heterocycles including pyrroles, indoles, and thiophenes of varied substitution. Mechanistic studies implicate an initial P-N cooperative activation of HBpin by1to giveP-hydrido diazaphospholene2, which is diverted by Atherton-Todd oxidation with chloroalkane to generateP-chloro diazaphospholene3. DFT calculations suggest subsequent oxidation of pinacolborane by3generates chloropinacolborane (ClBpin) as a transient electrophilic borylating species, consistent with observed substituent effects and regiochemical outcomes. These results illustrate the targeted diversion of established reaction pathways in organophosphorus catalysis to enable a new mode of main group-catalyzed C-H borylation.

Isodesmic C-H Borylation: Perspectives and Proof of Concept of Transfer Borylation Catalysis

Rochette, étienne,Desrosiers, Vincent,Soltani, Yashar,Fontaine, Frédéric-Georges

, p. 12305 - 12311 (2019/08/20)

The potential advantages of using arylboronic esters as boron sources in C-H borylation are discussed. The concept is showcased using commercially available 2-mercaptopyridine as a metal-free catalyst for the transfer borylation of heteroarenes using arylboronates as borylation agents. The catalysis shows a unique functional group tolerance among C-H borylation reactions, tolerating notably terminal alkene and alkyne functional groups. The mechanistic investigation is also described.
