Check Digit Verification of cas no

The CAS Registry Mumber 1422558-61-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,5,5 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1422558-61:
(9*1)+(8*4)+(7*2)+(6*2)+(5*5)+(4*5)+(3*8)+(2*6)+(1*1)=149
149 % 10 = 9
So 1422558-61-9 is a valid CAS Registry Number.

Copper(I)-catalyzed borylative exo -cyclization of alkenyl halides containing unactivated double bond

Kubota, Koji,Yamamoto, Eiji,Ito, Hajime

, p. 2635 - 2640 (2013/03/29)

A borylative exo-cyclization of alkenyl halides has been reported. The reaction includes the regioselective addition of a borylcopper(I) intermediate to unactivated terminal alkenes, followed by the intramolecular substitution of the resulting alkylcopper(I) moiety for the halide leaving groups. Experimental and theoretical investigations of the reaction mechanism have also been described. This reaction provides a new method for the synthesis of alkylboronates containing strained cycloalkyl structures from simple starting materials.
