7440-27-9 Usage
General Description
Terbium is a rare earth metal with the atomic number 65 and the symbol Tb. It is a silvery-white, malleable, and ductile metal that is relatively stable in air. Terbium is primarily used in the production of electronic devices, such as color television tubes, fluorescent lamps, and fuel cells. It also has important applications in the production of sonar systems, nuclear reactors, and magnetic resonance imaging (MRI) machines. Terbium compounds are utilized as phosphors in various optical materials, including X-ray contrast agents and solid-state lasers. Additionally, terbium is used in the production of advanced alloys, magnetos, and catalysts. Due to its scarcity, terbium is considered a valuable and strategic resource in the field of technology and industry.
Check Digit Verification of cas no
The CAS Registry Mumber 7440-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,4 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7440-27:
(6*7)+(5*4)+(4*4)+(3*0)+(2*2)+(1*7)=89
89 % 10 = 9
So 7440-27-9 is a valid CAS Registry Number.
