Check Digit Verification of cas no

The CAS Registry Mumber 1283075-21-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,0,7 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1283075-21:
(9*1)+(8*2)+(7*8)+(6*3)+(5*0)+(4*7)+(3*5)+(2*2)+(1*1)=147
147 % 10 = 7
So 1283075-21-7 is a valid CAS Registry Number.

Cu(I)-Catalyzed Alkynylation of Quinolones

Harutyunyan, Syuzanna R.,Lemaire, Sebastien,Maestro, Aitor

supporting information, (2022/02/14)

Herein we report the first alkynylation of quinolones with terminal alkynes under mild reaction conditions. The reaction is catalyzed by Cu(I) salts in the presence of a Lewis acid, which is essential for the reactivity of the system. The enantioselective version of this transformation has also been explored, and the methodology has been applied in the synthesis of the enantioenriched tetrahydroquinoline alkaloid cuspareine.
