19711-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19711-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,1 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19711-56:
(7*1)+(6*9)+(5*7)+(4*1)+(3*1)+(2*5)+(1*6)=119
119 % 10 = 9
So 19711-56-9 is a valid CAS Registry Number.

Electrochemistry Enabled Nickel-Catalyzed Selective C?S Bond Coupling Reaction

Pan, Yi,Wang, Yang,Wang, Yi,Zhang, Feng

supporting information, (2022/02/16)

This work describes an electrochemical enabled nickel-catalyzed chemoselective C?S bond coupling protocol for the production of aryl sulfides and sulfones. By simply switching the nickel catalysts and electrodes, this electrochemical C?S bond coupling has demonstrated excellent redox activity, scalability and sustainability. Furthermore, the mechanism for this electrochemical cross-coupling reaction has been investigated.
