HCFC-251, also known as 1,1,1,3,3-pentafluoropropane, is a hydrochlorofluorocarbon that serves as a refrigerant and a propellant in aerosol products. It is a colorless, odorless gas characterized by its low toxicity and flammability. With a relatively low global warming potential, HCFC-251 is considered a more environmentally friendly alternative to chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs). However, its ozone-depleting potential has led to its production and use being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer, prompting the adoption of more sustainable and eco-friendly alternatives.

Uses

Used in Refrigeration Industry:
HCFC-251 is used as a refrigerant for its low toxicity and flammability, providing a safer and more environmentally friendly option compared to traditional refrigerants like CFCs and HFCs.
Used in Aerosol Products Industry:
HCFC-251 is used as a propellant in aerosol products due to its low toxicity and ability to provide effective product dispensing.
However, due to its ozone-depleting potential, the use of HCFC-251 is being phased out, and industries are transitioning to more sustainable and eco-friendly alternatives to minimize environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 421-41-0 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 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 421-41:
(5*4)+(4*2)+(3*1)+(2*4)+(1*1)=40
40 % 10 = 0
So 421-41-0 is a valid CAS Registry Number.
