4923-66-4 Usage
General Description
1,2,3,4-tetrahydroanthracene-9,10-dione, also known as tetrahydroanthraquinone, is a chemical compound with the molecular formula C14H10O2. It is a derivative of anthraquinone and is often synthesized through the hydrogenation of anthraquinone. 1,2,3,4-tetrahydroanthracene-9,10-dione is a yellowish crystalline solid that is sparingly soluble in water but more soluble in organic solvents. It is used in the manufacturing of dyes, as well as in the synthesis of pharmaceuticals and other organic compounds. Tetrahydroanthraquinone has also been studied for its potential antioxidant and anti-inflammatory properties. However,
Check Digit Verification of cas no
The CAS Registry Mumber 4923-66-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4923-66:
(6*4)+(5*9)+(4*2)+(3*3)+(2*6)+(1*6)=104
104 % 10 = 4
So 4923-66-4 is a valid CAS Registry Number.

Colloid and nanodimensional catalysts in organic synthesis: VI.1 Hydrogenation and hydrogenolysis of carbonyl compounds
Mokhov,Popov,Nebykov
, p. 1656 - 1661 (2015/01/09)
Aldehydes and ketones are found to be hydrogenated to alcohols with hydrogen at atmospheric pressure under the catalysis with nickel nanoparticles. The reaction under study may be used as technologically available and cheap method for hydrogenation of carbonyl groups. It is found that in the case of aromatic ketones hydrogenolysis of C=O bond with partial hydrogenation of aromatic groups takes place.
