Check Digit Verification of cas no

The CAS Registry Mumber 92197-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,9 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92197-18:
(7*9)+(6*2)+(5*1)+(4*9)+(3*7)+(2*1)+(1*8)=147
147 % 10 = 7
So 92197-18-7 is a valid CAS Registry Number.

Palladium/norbornene-mediated tandem C-H amination/C-I alkenylation reaction of aryl iodides with secondary cyclic O-benzoyl hydroxylamines and activated terminal olefins

Chen, Zhi-Yuan,Ye, Chang-Qing,Zhu, Hui,Zeng, Xing-Ping,Yuan, Jian-Jun

, p. 4237 - 4241 (2014)

A novel palladium-catalyzed norbornene-mediated three-component reaction for the construction of ortho-alkenyl aromatic tertiary amines has been achieved, which represents a useful extension of the Catellani-type tandem ortho-selective C-H amination trans

Copper-Catalyzed Three-Component Carboamination of Arynes: Expeditious Synthesis of o-Alkynyl Anilines and o-Benzoxazolyl Anilines

Niu, Sheng-Li,Hu, Jiangtao,He, Kuicheng,Chen, Ying-Chun,Xiao, Qing

supporting information, p. 4250 - 4254 (2019/06/07)

A copper-catalyzed three-component reaction of in situ formed arynes, terminal alkynes, and O-benzoylhydroxylamines has been developed. By adjusting reaction conditions, the nucleophiles in this transformation can be extended from terminal alkynes to benzoxazoles. These procedures provide a modular and facile approach to o-alkynyl anilines and o-benzoxazolyl anilines from easily available substrates in only one step.

Synthesis of hindered anilines: Copper-catalyzed electrophilic amination of aryl boronic esters

Rucker, Richard P.,Whittaker, Aaron M.,Dang, Hester,Lalic, Gojko

supporting information; experimental part, p. 3953 - 3956 (2012/06/04)

No longer a hindrance: Copper-catalyzed electrophilic amination of aryl boronic esters is accomplished under mild reaction conditions using 2.5-5.0 mol % of a catalyst derived from copper tert-butoxide and Xantphos ligand (see scheme). The reaction tolerates a wide range of functional groups and can be used to prepare some of the most hindered anilines made to date. Copyright
