473980-96-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 473980-96-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,9,8 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 473980-96:
(8*4)+(7*7)+(6*3)+(5*9)+(4*8)+(3*0)+(2*9)+(1*6)=200
200 % 10 = 0
So 473980-96-0 is a valid CAS Registry Number.

A concise enantioselective strategy to (+)-(R)-goniothalamin and (+)-(R)-goniothalamin oxide by employing hydrolytic kinetic resolution and ring-closing metathesis as key steps

Bose, D. Subhas,Reddy, A. V. Narsimha,Srikanth, Bingi

body text, p. 2323 - 2326 (2009/04/04)

An efficient and general strategy to (R)-goniothalamin and (R)-goniothalamin oxide is described by using Jacobsen's hydrolytic kinetic resolution of racemic epoxide and ring-closing metathesis (RCM) as key steps, which provided a rapid access to these natural products that display a fascinating array of biological activity. (R)-Goniothalamin oxide was prepared in high yield and diastereomeric excess under various epoxidation conditions. Georg Thieme Verlag Stuttgart.
