Check Digit Verification of cas no

The CAS Registry Mumber 99956-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,5 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99956-90:
(7*9)+(6*9)+(5*9)+(4*5)+(3*6)+(2*9)+(1*0)=218
218 % 10 = 8
So 99956-90-8 is a valid CAS Registry Number.

Oxidation and Reduction Products of Some (Hydroxy)monoterpenones

Brieskorn, Carl Heinz,Ryu, Chung-Kyu

, p. 788 - 800 (1985)

The alcoholic group of the hydroxymethyl derivatives of thujan-3-one, pinan-3-one, caran-3-one, p-menthan-2-one and p-menthan-3-one is oxidized to the carboxy group or reduced to the methyl group.Some intermediates are also produced.Differences in the reactivities of bicyclic and monocyclic monoterpenones are discussed.
