Check Digit Verification of cas no

The CAS Registry Mumber 1232977-24-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,2,9,7 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1232977-24:
(9*1)+(8*2)+(7*3)+(6*2)+(5*9)+(4*7)+(3*7)+(2*2)+(1*4)=160
160 % 10 = 0
So 1232977-24-0 is a valid CAS Registry Number.

Copper-catalyzed alkynylation of amides with potassium alkynyltrifluoroborates: A room-temperature, base-free synthesis of ynamides

Jouvin, Kevin,Couty, Francois,Evano, Gwilherm

supporting information; experimental part, p. 3272 - 3275 (2010/10/21)

(Figure Presented) An efficient copper-mediated method for the coupling of potassium alkynyltrifluoroborates with nitrogen nucleophiles is reported. This reaction provides the first base-free and room-temperature synthesis of ynamides and allows for an easy preparation of these useful building blocks.
