Check Digit Verification of cas no

The CAS Registry Mumber 220316-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220316-75:
(8*2)+(7*2)+(6*0)+(5*3)+(4*1)+(3*6)+(2*7)+(1*5)=86
86 % 10 = 6
So 220316-75-6 is a valid CAS Registry Number.

Copper-Catalyzed Enantioselective Sonogashira Type Coupling of Alkynes with α-Bromoamides

Chen, Bin,Mo, Xueling,Zhang, Guozhu

supporting information, p. 13998 - 14002 (2020/06/10)

An asymmetric copper-catalyzed Sonogashira type coupling between alkynes and α-bromoamides has been developed. This method represents a facile approach to synthetically useful β, γ-alkynyl amides from two readily available starting materials in a highly enantioselective manner. A Bisoxazoline diphenylanaline (BOPA) serves as the effective chiral ligand. Preliminary mechanistic studies support the formation of alkyl radical species.
