Check Digit Verification of cas no

The CAS Registry Mumber 1569075-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,0,7 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1569075-99:
(9*1)+(8*5)+(7*6)+(6*9)+(5*0)+(4*7)+(3*5)+(2*9)+(1*9)=215
215 % 10 = 5
So 1569075-99-5 is a valid CAS Registry Number.

Stereoselective construction of the ABC-ring system of fusidane triterpenes via intermolecular/transannular Michael reaction cascade

Fujii, Tomohiro,Nakada, Masahisa

, p. 1597 - 1601 (2014/03/21)

A stereoselective construction of the ABC-ring system of fusidane triterpenes via intermolecular/transannular Michael reaction cascade is described. The substrate, a ten-membered carbocyclic ketone, has been successfully prepared by the Cr-mediated intramolecular alkenylation of the corresponding acyclic compound. The array of functionalities in the product stereoselectively obtained by the cascade reaction is useful for further structural modifications directed toward the total synthesis of fusidane and other triterpenes, and designed molecules intended for studying structure-activity relationships.
