16737-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16737-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,3 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16737-31:
(7*1)+(6*6)+(5*7)+(4*3)+(3*7)+(2*3)+(1*1)=118
118 % 10 = 8
So 16737-31-8 is a valid CAS Registry Number.

A novel nickel-catalyzed synthesis of thioesters, esters and amides from aryl iodides in the presence of chromium hexacarbonyl

Iranpoor, Nasser,Firouzabadi, Habib,Etemadi-Davan, Elham,Nematollahi, Arash,Firouzi, Hamid Reza

, p. 6445 - 6452 (2015/08/11)

This study describes our findings on a novel and cheap NiCl2 catalytic system under ligand-free conditions for the efficient thiocarbonylation, alkoxycarbonylation and amidocarbonylation reactions of aryl iodides in the presence of Cr(CO)6 as the solid source of carbon monoxide under air. A variety of aryl iodides tolerated the reaction conditions and structurally different thiols, alcohols and amines were used efficiently. The corresponding thioesters, esters and amides were obtained in good to excellent yield at atmospheric pressure under mild reaction conditions.
