Check Digit Verification of cas no

The CAS Registry Mumber 23173-24-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,7 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23173-24:
(7*2)+(6*3)+(5*1)+(4*7)+(3*3)+(2*2)+(1*4)=82
82 % 10 = 2
So 23173-24-2 is a valid CAS Registry Number.

Syntheses and Cardiovascular Activity of Stereoisomers and Derivatives of Eburnane Alkaloids

Czibula, Laszlo,Nemes, Andras,Visky, Gyoergy,Farkas, Maria,Szombathelyi, Zsolt,et al.

, p. 221 - 230 (2007/10/02)

The synthesis of all the possible isomers of the eburnamenine-vincamine type alkaloids 1b, 2a*, 3a and derivatives 4, 8, 9, 10 is described.Structures were determined by 1H- and 13C-NMR spectroscopy including special techniques such as DR, DEPT, DNOE, and 2D-HSC.In contrast to the known cerebrovascular effects of cis-(3S,16S) compounds, trans-(3S,16R) derivatives show a significant peripheral vasodilator effect. Key Word: Eburnanes / Alkaloids / Cardiovascular effects / Indoloquinolizines
