755-21-5 Usage
General Description
1,1,2,2,3,3,4,4-Octafluoro-5-chloropentane is a chemical compound with the molecular formula C5F8Cl. It is a colorless, odorless liquid that is used as a refrigerant and a blowing agent in the production of foam insulation. 1,1,2,2,3,3,4,4-Octafluoro-5-chloropentane is known for its low global warming potential and ozone depletion potential, making it an environmentally friendly alternative to other refrigerants. It has a boiling point of -6.8°C and is considered to be relatively non-toxic, although prolonged exposure to high concentrations may cause irritation to the respiratory system. 1,1,2,2,3,3,4,4-Octafluoro-5-chloropentane is commonly used in the production of refrigeration and air conditioning systems, as well as in foam insulation applications.
Check Digit Verification of cas no
The CAS Registry Mumber 755-21-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 755-21:
(5*7)+(4*5)+(3*5)+(2*2)+(1*1)=75
75 % 10 = 5
So 755-21-5 is a valid CAS Registry Number.
