207120-52-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 207120-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,1,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 207120-52:
(8*2)+(7*0)+(6*7)+(5*1)+(4*2)+(3*0)+(2*5)+(1*2)=83
83 % 10 = 3
So 207120-52-3 is a valid CAS Registry Number.

Amine-promoted asymmetric (4+2) annulations for the enantioselective synthesis of tetrahydropyridines: A traceless and recoverable auxiliary strategy

Hu, Pengfei,Hu, Jian,Jiao, Jiajun,Tong, Xiaofeng

, p. 5319 - 5322 (2013)

Gone, without a trace: The in situ reaction of 2-(acetoxymethyl)buta-2,3- dienoate and a secondary amine produces a 2-methylene-3-oxobutanoate equivalent that can be used in asymmetric [4+2] annulations with N-tosylimines to provide tetrahydropyridines in

Design and synthesis of novel conformationally restricted HIV protease inhibitors

Salituro, Francesco G.,Baker, Christopher T.,Court, John J.,Deininger, David D.,Kim, Eunice E.,Li, Biquin,Novak, Perry M.,Rao, Bhisetti G.,Pazhanisamy,Porter, Margaret D.,Schairer, Wayne C.,Tung, Roger D.

, p. 3637 - 3642 (2007/10/03)

A set of HIV protease inhibitors represented by compound 2 has previously been described. Structural and conformational analysis of this compound suggested that conformational restriction of the P1/P2 portion of the molecule could lead to a novel set of potent protease inhibitors. Thus, probe compounds 3-7 were designed, synthesized, and found to be potent inhibitors of HIV protease.
