421-41-0 Usage
General Description
HCFC-251, also known as 1,1,1,3,3-pentafluoropropane, is a hydrochlorofluorocarbon used as a refrigerant and a propellant in aerosol products. It is a colorless, odorless gas with low toxicity and flammability. HCFC-251 has a relatively low global warming potential, making it a more environmentally friendly alternative to other refrigerants such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs). However, due to its ozone-depleting potential, its production and use are being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer. As a result, HCFC-251 is being replaced by more sustainable and eco-friendly alternatives in various industrial and consumer applications.
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.
