Check Digit Verification of cas no
The CAS Registry Mumber 203047-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,4 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 203047-07:
(8*2)+(7*0)+(6*3)+(5*0)+(4*4)+(3*7)+(2*0)+(1*7)=78
78 % 10 = 8
So 203047-07-8 is a valid CAS Registry Number.

Stereoselective synthesis of the core structure of the protein phosphatase inhibitor dysidiolide
Brohm, Dirk,Waldmann, Herbert
, p. 3995 - 3998 (2007/10/03)
The core structure of the protein phosphatase inhibitor dysidiolide and analogs thereof were built up in high yields and with high diastereomer ratios by Diels-Alder reaction between an appropriate diene and an α,β- unsaturated aldehyde.
