35537-97-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35537-97-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,5,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35537-97:
(7*3)+(6*5)+(5*5)+(4*3)+(3*7)+(2*9)+(1*7)=134
134 % 10 = 4
So 35537-97-4 is a valid CAS Registry Number.

Catalytic asymmetric torgov cyclization: A concise total synthesis of (+)-estrone

Prevost, Sebastien,Dupre, Nathalie,Leutzsch, Markus,Wang, Qinggang,Wakchaure, Vijay,List, Benjamin

supporting information, p. 8770 - 8773 (2014/08/18)

An asymmetric Torgov cyclization, catalyzed by a novel, highly Bronsted acidic dinitro-substituted disulfonimide, is described. The reaction delivers the Torgov diene and various analogues with excellent yields and enantioselectivity. This method was applied in a very short synthesis of (+)-estrone.
