Check Digit Verification of cas no

The CAS Registry Mumber 130288-43-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,8 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130288-43:
(8*1)+(7*3)+(6*0)+(5*2)+(4*8)+(3*8)+(2*4)+(1*3)=106
106 % 10 = 6
So 130288-43-6 is a valid CAS Registry Number.

Biomimetic studies towards the C28-C40 polycyclic domain of the azaspiracids

Aiguade, Josep,Hao, Junliang,Forsyth, Craig J.

, p. 817 - 820 (2007/10/03)

An acyclic intermediate representing a putative biomimetic precursor of the C28-C40 domain of the novel marine toxin azaspiracid was constructed convergently from C28-C34 and C35-C40 fragments. In studying the assembly of the C28-C34 dioxabicyclo[3.3.1]nonane system via an intramolecular hetero-conjugate addition upon a C34-C36 enone, a stereoselective C-Michael addition intervened to provide a highly substituted cyclohexane.
