423-22-3 Usage
General Description
2,2,3,3,4,4,5-heptafluoro-5-(heptafluoropropyl)tetrahydrofuran is a chemical compound with the molecular formula C7HF13O. It is a colorless, volatile liquid with a sweet odor, and it is highly flammable. Furan, 2,2,3,3,4,4,5-heptafluoro-5-(heptafluoropropyl)tetrahydro- is commonly used as a refrigerant, solvent, and as an intermediate in the production of various chemicals. It is also used as a propellant in aerosol products and as a blowing agent in the production of foam plastics. Additionally, it is a greenhouse gas and has been found to contribute to ozone depletion. Due to its environmental and health effects, its use is being regulated and alternative compounds are being sought for many of its applications.
Check Digit Verification of cas no
The CAS Registry Mumber 423-22-3 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 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 423-22:
(5*4)+(4*2)+(3*3)+(2*2)+(1*2)=43
43 % 10 = 3
So 423-22-3 is a valid CAS Registry Number.
