53166-66-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53166-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,6 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 53166-66:
(7*5)+(6*3)+(5*1)+(4*6)+(3*6)+(2*6)+(1*6)=118
118 % 10 = 8
So 53166-66-8 is a valid CAS Registry Number.

Co2(CO)8as a Solid CO (g) Source for the Amino Carbonylation of (Hetero)aryl Halides with Highly Deactivated (Hetero)arylamines

Carbonylation of (hetero)aryl iodides/bromides with highly deactivated 2-aminopyridines using Pd-Co(CO)4 bimetallic catalysis is accomplished. The use of Co2(CO)8 as a solid CO(g) source enhanced reaction rates observed when compared to CO(g), and excellent yields highlight the versatility of the developed protocol. A wide range of electronically and sterically demanding heterocyclic amines and (hetero)aryl iodides/bromides employed for this study resulted in excellent yields of amino carbonylated products. The developed methodology was further extended to synthesize Trypanosome brucie and luciferase inhibitors.
