394739-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 394739-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,4,7,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 394739-38:
(8*3)+(7*9)+(6*4)+(5*7)+(4*3)+(3*9)+(2*3)+(1*8)=199
199 % 10 = 9
So 394739-38-9 is a valid CAS Registry Number.

Towards colombiasin A
Harrowven, David C,Tyte, Melloney J
, p. 8709 - 8711 (2007/10/03)
A synthetic route to an unnatural diastereoisomer of colombiasin A is described. Key features are an arene alkylation with a γ-methylene-γ-butyrolactone and an intramolecular Diels-Alder cycloaddition.
