5202-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5202-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5202-83:
(6*5)+(5*2)+(4*0)+(3*2)+(2*8)+(1*3)=65
65 % 10 = 5
So 5202-83-5 is a valid CAS Registry Number.

Nickel-Catalyzed Asymmetric Synthesis of α-Arylbenzamides

Cuesta-Galisteo, Sergio,Sch?rgenhumer, Johannes,Wei, Xiaofeng,Merino, Estíbaliz,Nevado, Cristina

supporting information, p. 1605 - 1609 (2020/12/01)

A nickel-catalyzed asymmetric reductive hydroarylation of vinyl amides to produce enantioenriched α-arylbenzamides is reported. The use of a chiral bisimidazoline (BIm) ligand, in combination with diethoxymethylsilane and aryl halides, enables the regioselective introduction of aryl groups to the internal position of the olefin, forging a new stereogenic center α to the N atom. The use of neutral reagents and mild reaction conditions provides simple access to pharmacologically relevant motifs present in anticancer, SARS-CoV PLpro inhibitors, and KCNQ channel openers.
