Check Digit Verification of cas no

The CAS Registry Mumber 23412-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23412-22:
(7*2)+(6*3)+(5*4)+(4*1)+(3*2)+(2*2)+(1*2)=68
68 % 10 = 8
So 23412-22-8 is a valid CAS Registry Number.

ARYLTETRALIN LIGNANS FROM PODOPHYLLUM HEXANDRUM AND PODOPHYLLUM PELTATUM

Jackson, David E.,Dewick, Paul M.

, p. 1147 - 1152 (1984)

Roots of Podophyllum hexandrum and P. peltatum contain the same range of ten aryltetralin lignans: podophyllotoxin, 4'-demethylpodophyllotoxin, α-peltatin, β-peltatin, desoxypodophyllotoxin, podophyllotoxone, isopicropodophyllone, 4'-demetyldesoxypodophyllotoxin, 4'-demethylpodophyllotoxone and 4'-demethylisopicropodophyllone, although the relative proportions are markedly different.The latter two compounds are previously unreported natural products, but 4'-demethylisopicropodophyllone may well be an artefact resulting from epimerization of 4'-demethylpodophyllotoxone.The peltatins have not previously been isolated from P. hexandrum.Key Word Index - Podophyllum hexandrum; P. peltatum; Podophyllaceae; aryltetralin; lignans; podophyllotoxin.
