Check Digit Verification of cas no

The CAS Registry Mumber 19210-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,1 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19210-13:
(7*1)+(6*9)+(5*2)+(4*1)+(3*0)+(2*1)+(1*3)=80
80 % 10 = 0
So 19210-13-0 is a valid CAS Registry Number.

Chemistry and Stereochemistry of Iridoids, V. - Crystal and Molecular Structure of Hexaacetylleonuride - Stereochemical Correlations of Some Iridoid Glucosides

Weinges, Klaus,Zourari, Maria,Smuda, Hubert,Rodewald, Hans,Nixdorf, Matthias,Irngartinger, Hermann

, p. 1063 - 1081 (2007/10/02)

Leonuride (ajugol, 1a) and myoporoside (2) are C-6 epimers, the configurations of which are specified differently in the literature.By X-ray structure analysis of hexaacetylleonuride (1d) the absolute configuration of leonuride (1a) is fixed, to which the configurations of catalpol (3a), antirrhinoside (6a), and harpagide (7a) as well as procumbide (14a) and 6-epi-harpagide (15a) are linked by chemical correlation.
