602-73-3 Usage
General Description
1,3-Dichloroanthraquinone is a chemical compound that belongs to the class of organic compounds known as anthraquinones. It is a derivative of anthraquinone with two chlorine atoms attached at positions 1 and 3 of the molecule. 1,3-Dichloroanthraquinone is a yellow-orange solid with a melting point of 204-206°C and is insoluble in water. 1,3-Dichloroanthraquinone is mainly used in the production of vat dyes, which are widely used in the textile industry. It is also used as a reagent in organic synthesis and as a precursor in the manufacturing of pharmaceuticals and other organic compounds. Additionally, it has potential applications in the field of electronics and materials science. However, it is important to handle 1,3-dichloroanthraquinone with caution as it is considered harmful if swallowed, inhaled, or absorbed through the skin, and can cause irritation to the eyes, skin, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 602-73-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 602-73:
(5*6)+(4*0)+(3*2)+(2*7)+(1*3)=53
53 % 10 = 3
So 602-73-3 is a valid CAS Registry Number.
