Check Digit Verification of cas no
The CAS Registry Mumber 2643-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2643-25:
(6*2)+(5*6)+(4*4)+(3*3)+(2*2)+(1*5)=76
76 % 10 = 6
So 2643-25-6 is a valid CAS Registry Number.

Herein, a copper-catalyzed C?F bond defluorosilylation reaction of tetrafluoroethylene and other polyfluoroalkenes is described. Mechanistic studies, based on a series of stoichiometric reactions with copper complexes, revealed that the key steps of this defluorosilylation reaction are 1) the 1,2-addition of a silylcopper intermediate to the polyfluoroalkene and 2) a subsequent selective β-fluorine elimination, which generates a Cu?F species. The β-fluorine elimination is facilitated by Lewis acidic F?Bpin, which is generated in situ during the defluorosilylation.
