12034-59-2 Usage
General Description
Niobium(IV) oxide is a chemical compound with the formula NbO2. It is an inorganic substance that appears as a black or bluish-black powder. Niobium(IV) oxide's key characteristic is its metallic conductivity which is due to niobium's oxidation state; instead of a typical +5 state, it carries a +4 state in this compound. The lower oxidation allows for the donation and acceptance of electrons, leading to the compound's metallic characteristic. It is generally used as an additive in the production of special optical glasses and as a catalyst in certain chemical reactions. Niobium(IV) oxide can cause irritation to the eyes and skin upon exposure, and inhalation may cause respiratory irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 12034-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12034-59:
(7*1)+(6*2)+(5*0)+(4*3)+(3*4)+(2*5)+(1*9)=62
62 % 10 = 2
So 12034-59-2 is a valid CAS Registry Number.
