1344-70-3 Usage
Chemical Properties
Brownish-black powder. Soluble in acids; difficultly soluble
in water.
Uses
COPPER(II) OXIDE can be used as ceramic colorant, reagent in analytical chemistry, insecticide for potato plants, catalyst, purification of hydrogen, batteries and electrodes, aromatic acids from cresols, electroplating, solvent for chromic iron ores, desulfurizing oils, rayon, metallurgical and welding fluxes, antifouling paints, phosphors.
Definition
ChEBI: A metal oxide that has the formula CuO. It has an ionic structure.
Hazard
Toxic by ingestion.
Industrial uses
Cuprous oxide (Cu2O) and cupric oxide orblack CuO are used in ceramics. Cupric oxideis generally preferred in glazes and cuprousoxide in glasses.Cupric oxide, when used in glazes, has awide range of color. It may be used either asthe raw oxide in a raw glaze, as the raw oxidein a fritted glaze, or as part of the frit itself.
Check Digit Verification of cas no
The CAS Registry Mumber 1344-70-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1344-70:
(6*1)+(5*3)+(4*4)+(3*4)+(2*7)+(1*0)=63
63 % 10 = 3
So 1344-70-3 is a valid CAS Registry Number.
