420-43-9 Usage
Uses
Used in Refrigeration Industry:
1-Bromo-1,1-difluoroethane is used as a refrigerant for its ability to maintain low temperatures in cooling systems, providing an efficient means for thermal regulation in various applications.
Used in Aerosol Propellants:
In the aerosol industry, 1-Bromo-1,1-difluoroethane serves as a propellant, enabling the ejection of substances from aerosol cans, which is crucial for products such as spray paints, deodorants, and other consumer goods.
Used in Cleaning and Degreasing Products:
As a solvent in cleaning and degreasing products, 1-Bromo-1,1-difluoroethane is utilized for its capacity to dissolve and remove contaminants, grease, and oils from surfaces, making it valuable in industrial and commercial cleaning processes.
However, due to its harmful effects on human health and the environment, the use of 1-Bromo-1,1-difluoroethane is becoming increasingly restricted and regulated, necessitating the development of safer alternatives for these applications.
Check Digit Verification of cas no
The CAS Registry Mumber 420-43-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 420-43:
(5*4)+(4*2)+(3*0)+(2*4)+(1*3)=39
39 % 10 = 9
So 420-43-9 is a valid CAS Registry Number.
