199465-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 199465-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,6 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199465-55:
(8*1)+(7*9)+(6*9)+(5*4)+(4*6)+(3*5)+(2*5)+(1*5)=199
199 % 10 = 9
So 199465-55-9 is a valid CAS Registry Number.

Cobalt-Catalyzed Oxidative Homocoupling of Arylzinc Species

Bourne-Branchu, Yann,Moncomble, Aurélien,Corpet, Martin,Danoun, Gregory,Gosmini, Corinne

, p. 3352 - 3356 (2016)

A novel procedure for the synthesis of functionalized symmetrical biaryl compounds is described. The reaction proceeds via the oxidative homocoupling of arylzinc species formed by cobalt catalysis in the presence of air or p-benzoquinone depending on the nature of the functional group.

Cobalt-catalyzed electrophilic amination of arylzincs with N-chloroamines

Qian, Xin,Yu, Zailu,Auffrant, Audrey,Gosmini, Corinne

supporting information, p. 6225 - 6229 (2013/07/05)

Roles reversed: An efficient cobalt-catalyzed electrophilic amination of arylzinc reagents has been achieved. A variety of functionalized arylzincs and N-chloroamines were coupled under mild conditions (see scheme). Both secondary and tertiary arylamines were obtained in moderate to excellent yields.
