71086-78-7 Usage

Uses

Used in Aerospace Industry:
Helium is used as a lifting gas for balloons and airships due to its low density and non-flammable properties, providing a safer and more efficient alternative to hydrogen.
Used in Cryogenics:
Helium is used as a coolant in cryogenic applications, taking advantage of its low boiling point and excellent thermal conductivity.
Used in Nuclear Industry:
Helium is used as a coolant for nuclear reactors, benefiting from its inert nature and ability to transfer heat effectively without reacting with other elements.
Used in Deep-Sea Diving:
Helium is used in breathing mixtures for deep-sea diving, reducing the risk of nitrogen narcosis and decompression sickness due to its lower solubility in blood and tissues compared to nitrogen.
Used in High-Tech Applications:
Helium is used in various high-tech applications, such as in the production of semiconductors, fiber optics, and scientific research, due to its unique properties and limited availability, making it a valuable and in-demand chemical element.

Check Digit Verification of cas no

The CAS Registry Mumber 71086-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,8 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71086-78:
(7*7)+(6*1)+(5*0)+(4*8)+(3*6)+(2*7)+(1*8)=127
127 % 10 = 7
So 71086-78-7 is a valid CAS Registry Number.
