Check Digit Verification of cas no

The CAS Registry Mumber 1439386-58-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1439386-58:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*8)+(3*6)+(2*5)+(1*8)=199
199 % 10 = 9
So 1439386-58-9 is a valid CAS Registry Number.

Ni-Catalyzed Denitrogenative Cross-Coupling of Benzotriazinones and Cyclopropanols: An Easy Access to Functionalized β-Aryl Ketones

Li, Jincan,Zheng, Yan,Huang, Mingxian,Li, Wanfang

supporting information, p. 5020 - 5024 (2020/07/03)

A novel Ni-catalyzed denitrogenative cross-coupling between benzotriazinones and cyclopropanols is reported herein. This neoteric reactivity allows for the convenient synthesis of β-(o-amido)aryl ketones from readily available starting materials with good yields (up to 93percent) and general substrate scope.

Palladium-catalyzed cross-coupling of cyclopropanol-derived ketone homoenolates with aryl bromides

Rosa, David,Orellana, Arturo

supporting information, p. 5420 - 5422 (2013/06/27)

The cross-coupling reaction of cyclopropanol-derived ketone homoenolates bearing β-hydrogens with aryl and hetaryl bromides has been achieved for the first time. This reaction is high yielding, is broad in scope and uses a simple catalytic system. Notably, the proposed palladium homoenolates do not undergo β-hydride elimination to the corresponding α,β- unsaturated ketones.
