Check Digit Verification of cas no

The CAS Registry Mumber 440677-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,6,7 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 440677-20:
(8*4)+(7*4)+(6*0)+(5*6)+(4*7)+(3*7)+(2*2)+(1*0)=143
143 % 10 = 3
So 440677-20-3 is a valid CAS Registry Number.

Asymmetric construction of the azaspiro[5.5]undec-8-ene system towards gymnodimine synthesis

Tsujimoto, Takashi,Ishihara, Jun,Horie, Mariko,Murai, Akio

, p. 399 - 402 (2007/10/03)

In the course of the synthetic studies on gymnodimine, a potent shellfish toxin, the asymmetric construction of the azaspirocyclic part was achieved by the (-)-siam·Cu(SbF6)2 complex catalyzed intermolecular Diels-Alder reaction in high exo- and enantioselectivities.
