Check Digit Verification of cas no

The CAS Registry Mumber 1239605-45-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,0 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1239605-45:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*0)+(3*5)+(2*4)+(1*5)=158
158 % 10 = 8
So 1239605-45-8 is a valid CAS Registry Number.

Nickel-Catalyzed Kumada Coupling of Boc-Activated Aromatic Amines via Nondirected Selective Aryl C-N Bond Cleavage

Zhang, Zheng-Bing,Ji, Chong-Lei,Yang, Ce,Chen, Jie,Hong, Xin,Xia, Ji-Bao

supporting information, p. 1226 - 1231 (2019/02/14)

A nickel-catalyzed Kumada coupling of aniline derivatives was developed by selective cleavage of aryl C-N bonds under mild reaction conditions. Without preinstallation of an ortho directing group on anilines, the cross-coupling reactions of Boc-protected aromatic amines with aryl Grignard reagents afforded unsymmetric biaryls. Mechanistic studies by DFT calculations revealed that the nickel-mediated C-N bond cleavage is the rate-limiting step.

Aryl ether as a Negishi coupling partner: An approach for constructing C-C bonds under mild conditions

Wang, Chao,Ozaki, Takashi,Takita, Ryo,Uchiyama, Masanobu

supporting information; experimental part, p. 3482 - 3485 (2012/05/04)

An etheric Negishi coupling: The first cross-coupling reaction between aryl alkyl ethers and dianion-type zincate reagents to afford biaryl compounds through selective cleavage of the etheric C(sp2)-O bond was developed. Dianion-type zincates showed excellent reactivity toward the aromatic ethers under mild conditions, with good functional group compatibility (see scheme). Copyright
