13967-76-5 Usage
General Description
Niobium is a chemical element with the symbol Nb and atomic number 41. It is a grey, ductile metal with a high melting point, and is commonly used in superalloys for jet and rocket engines, as well as in the construction of nuclear reactors and other high-temperature applications. It is also used in the production of high-strength, low-alloy steels and as a superconductor in magnetic resonance imaging (MRI) machines. Niobium is considered a "rare earth element" and is typically found in the minerals pyrochlore and columbite, with Brazil being the largest producer of niobium in the world.
Check Digit Verification of cas no
The CAS Registry Mumber 13967-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,6 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13967-76:
(7*1)+(6*3)+(5*9)+(4*6)+(3*7)+(2*7)+(1*6)=135
135 % 10 = 5
So 13967-76-5 is a valid CAS Registry Number.
