143112-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143112-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,1 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143112-20:
(8*1)+(7*4)+(6*3)+(5*1)+(4*1)+(3*2)+(2*2)+(1*0)=73
73 % 10 = 3
So 143112-20-3 is a valid CAS Registry Number.

Catalytic C-N and C-H Bond Activation: Ortho-Allylation of Benzoic Acids with Allyl Amines

Hu, Xiao-Qiang,Hu, Zhiyong,Zhang, Guodong,Sivendran, Nardana,Goo?en, Lukas J.

supporting information, p. 4337 - 4340 (2018/07/29)

A facile insertion of ruthenium into aromatic C-H and allylic C-N bonds are the key steps in a [Ru(p-cymene)Cl2]2-catalyzed ortho-C-H allylation of benzoic acids. This protocol allows drawing on the large pool of allylic amines for state-of-the-art ortho-functionalizations of arenes, turning neutral amines into leaving groups. Concise syntheses of biologically active compounds provide further evidence of the synthetic potential of this methodology.
