Check Digit Verification of cas no

The CAS Registry Mumber 916518-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,5,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 916518-57:
(8*9)+(7*1)+(6*6)+(5*5)+(4*1)+(3*8)+(2*5)+(1*7)=185
185 % 10 = 5
So 916518-57-5 is a valid CAS Registry Number.

Transition-Metal-Free ipso-Trifluoromethylthiolation of Lithium Aryl Boronates

Shen, Feng,Zheng, Hanliang,Xue, Xiao-Song,Lu, Long,Shen, Qilong

supporting information, p. 6347 - 6351 (2019/08/20)

A transition-metal-free direct trifluoromethylthiolation of the ipso-carbon of lithium aryl boronates with trifluoromethanesulfenate under mild conditions was described. In addition, late-stage site-selective C-H borylation/trifluoromethylation and C-Cl b

Ni-Catalyzed Borylation of Aryl Fluorides via C-F Cleavage

Liu, Xiang-Wei,Echavarren, Javier,Zarate, Cayetana,Martin, Ruben

supporting information, p. 12470 - 12473 (2015/10/19)

A Ni-catalyzed borylation via C-F activation is described. This protocol is distinguished by a wide scope, including unactivated fluoroarenes, without compromising its efficiency and scalability, thus representing a significant step-forward toward the implementation of C-F activation protocols.

Borylation of aryl and alkenyl carbamates through Ni-catalyzed C-O activation

Huang, Kun,Yu, Da-Gang,Zheng, Shu-Fang,Wu, Zhen-Hua,Shi, Zhang-Jie

experimental part, p. 786 - 791 (2011/03/20)

Direct borylation of aryl/alkenyl carbamates was developed through Ni catalysis. A broad substrate scope, including aryl, alkenyl, and heterocyclic derivatives, was studied. This study offers a convenient method to approach aryl/alkenyl boronic esters from phenol and ketone derivatives (see scheme). Copyright
