  • or
Niobium(IV) oxide, with the chemical formula NbO2, is an inorganic substance that appears as a black or bluish-black powder. It is characterized by its metallic conductivity, which is due to niobium's oxidation state in the compound being +4, instead of the typical +5 state. This lower oxidation state allows for the donation and acceptance of electrons, leading to the compound's metallic properties.

Safety Considerations:

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.
