Check Digit Verification of cas no

The CAS Registry Mumber 401916-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,9,1 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 401916-57:
(8*4)+(7*0)+(6*1)+(5*9)+(4*1)+(3*6)+(2*5)+(1*7)=122
122 % 10 = 2
So 401916-57-2 is a valid CAS Registry Number.

Catalytic Asymmetric Synthesis of α-Arylpyrrolidines and Benzo-fused Nitrogen Heterocycles

Dai, Xi-Jie,Engl, Oliver D.,León, Thierry,Buchwald, Stephen L.

supporting information, p. 3407 - 3411 (2019/02/24)

Herein, we report a practical two-step synthetic route to α-arylpyrrolidines through Suzuki–Miyaura cross-coupling and enantioselective copper-catalyzed intramolecular hydroamination reactions. The excellent stereoselectivity and broad scope for the transformation of substrates with pharmaceutically relevant heteroarenes render this method a practical and versatile approach for pyrrolidine synthesis. Additionally, this intramolecular hydroamination strategy facilitates the asymmetric synthesis of tetrahydroisoquinolines and medium-ring dibenzo-fused nitrogen heterocycles.

Olefins turned alkylating agents: Diastereoselective intramolecular Zr-catalyzed olefin alkylations

Cesati III, Richard R.,De Armas, Judith,Hoveyda, Amir H.

, p. 395 - 398 (2007/10/03)

(Equation Presented) 62% yield; 12 : 1 syn : anti The first examples of intramolecular Zr-catalyzed electrophilic alkylation of aryl olefins are disclosed. Substituted carbo-and heterocycles are prepared efficiently and diastereoselectively.
