Check Digit Verification of cas no

The CAS Registry Mumber 98665-32-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,6 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98665-32:
(7*9)+(6*8)+(5*6)+(4*6)+(3*5)+(2*3)+(1*2)=188
188 % 10 = 8
So 98665-32-8 is a valid CAS Registry Number.

ON THE CHEMISTRY OF INDIAN OCHIDACEAE PLANTS II. DENGIBSIN AND DENGIBSININ, THE FIRST NATURAL FLUORENONE DERIVATIVES FROM DENDROBIUM GIBSONII LINDL.

Talapatra, Sunil K.,Bose, Srabani,Mallik, Asok K.,Talapatra, Bani

, p. 2765 - 2770 (1985)

Dendrobium gibsonii, an Orchidaceae plant yielded the first natural fluorenone derivatives designated dengibsin and dengibsinin to which 1,5-dihydroxy-7-methoxy-9-fluorenone (1) and 1,6-dihydroxy-5,7-dimethoxy-9-fluorenone (2) structures have been assigned respectively.The structures are fully supported by the 1H-NMR, IR, UV and MS spectral data of dengibsis and dengibsinin and a number of their pertinent derivatives.Aurantiamide acetate, dimethyl terephthalate and β-sitosterol have been isolated as the other constituents.
