7439-90-9 Usage
Description
Krypton is a colorless, odorless, and tasteless noble gas that belongs to the Group 18 elements on the periodic table. It is produced through the distillation of liquid air and is known for its non-toxic and non-reactive properties, making it a valuable component in various industrial and scientific applications.
Uses
Used in Lighting and Photography:
Krypton is used as a lighting gas for its ability to emit a bright white light when electrically excited. This property makes it suitable for applications in lighting systems, such as fluorescent lamps and streetlights, as well as in photography for flashbulbs and strobe lights.
Used in Laser Systems:
Krypton is used as a lasing medium in the production of laser systems due to its unique spectral characteristics. It is particularly useful in high-powered laser applications, such as industrial cutting and welding, as well as in medical and scientific research.
Used in Anesthesia:
Krypton is used as a component in some types of anesthesia due to its non-toxic and non-reactive nature. It can be combined with other gases to create a stable and safe anesthetic mixture for medical procedures.
Used in Ion Propulsion Systems for Spacecraft:
Krypton is used in certain types of ion propulsion systems for spacecraft due to its inert properties. Its non-reactive nature allows it to be used as a propellant in these systems, enabling efficient and long-lasting propulsion for space missions.
Check Digit Verification of cas no
The CAS Registry Mumber 7439-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7439-90:
(6*7)+(5*4)+(4*3)+(3*9)+(2*9)+(1*0)=119
119 % 10 = 9
So 7439-90-9 is a valid CAS Registry Number.
