24265-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24265-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,6 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24265-21:
(7*2)+(6*4)+(5*2)+(4*6)+(3*5)+(2*2)+(1*1)=92
92 % 10 = 2
So 24265-21-2 is a valid CAS Registry Number.

Nickel-Catalyzed Conversion of Enol Triflates into Alkenyl Halides

Hofstra, Julie L.,Poremba, Kelsey E.,Shimozono, Alex M.,Reisman, Sarah E.

supporting information, p. 14901 - 14905 (2019/11/11)

A Ni-catalyzed halogenation of enol triflates was developed and it enables the synthesis of a broad range of alkenyl iodides, bromides, and chlorides under mild reaction conditions. The reaction utilizes inexpensive, bench-stable Ni(OAc)2?4 H2O as a precatalyst and proceeds at room temperature in the presence of sub-stoichiometric Zn and either 1,5-cyclooctadiene or 4-(N,N-dimethylamino)pyridine.
