General Description

Uranium disilicide is a chemical compound composed of uranium and silicon, with a chemical formula of USi2. It is a refractory ceramic material that exhibits high melting point and excellent mechanical properties, making it suitable for use in nuclear reactors and as a fuel for space propulsion systems. Uranium disilicide is also used as a semiconductor material in the production of electronic components. It is known for its high thermal conductivity and resistance to oxidation, as well as its ability to withstand high temperatures and harsh environments. However, it is important to handle uranium disilicide with caution due to its radioactive nature and potential health hazards associated with exposure.

Check Digit Verification of cas no

The CAS Registry Mumber 12039-85-9 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 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12039-85:
(7*1)+(6*2)+(5*0)+(4*3)+(3*9)+(2*8)+(1*5)=79
79 % 10 = 9
So 12039-85-9 is a valid CAS Registry Number.
