Check Digit Verification of cas no

The CAS Registry Mumber 17578-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,5,7 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 17578-82:
(7*1)+(6*7)+(5*5)+(4*7)+(3*8)+(2*8)+(1*2)=144
144 % 10 = 4
So 17578-82-4 is a valid CAS Registry Number.

Method for preparing alicyclic ketone by catalytic oxidation of alicyclic alcohol compound

-

Paragraph 0021; 0022, (2016/12/01)

The invention provides a method for preparing alicyclic ketone by catalytic oxidation of an alicyclic alcohol compound. The method takes air or oxygen as an oxidant and uses a catalyst system consisting two components of aza-adamantane free radical of nitroxide and a vanadium oxygen compound, and the alicyclic alcohol compound is oxidated into the corresponding alicyclic ketone with high selectivity at 50 to 120 DEG C. Compared with 2,2,6,6,-tetramethyl piperidine free radical of nitroxide, the aza-adamantane free radical of nitroxide has smaller influence of steric hindrance in a catalytic oxidation secondary alcohol reaction, and the catalyst system consisting of the vanadium oxygen compound has higher alicyclic alcohol oxidating efficiency. Compared with the conventional stoichiometric chemistry oxidation methods such as manganese dioxide, chromium trioxide and sodium hypochlorite, the method provided by the invention has the characteristics of few side products, mild reaction conditions, small environmental pollution and the like, and has very high practicability and economical efficiency.
