11126-05-9 Usage
General Description
Freon-11, also known as trichlorofluoromethane, is a chlorofluorocarbon (CFC) that was commonly used as a refrigerant in air conditioning and cooling systems. It is a colorless, odorless gas with a sweet, ethereal odor. Freon-11 has a relatively low boiling point and is non-flammable, making it an ideal choice for use in various cooling applications. However, it has been phased out in many countries due to its negative impact on the ozone layer. Exposure to Freon-11 can cause respiratory issues, skin irritation, and dizziness, and it is considered a potential environmental hazard. Efforts to replace Freon-11 with more environmentally friendly alternatives have been ongoing, in line with global efforts to protect the ozone layer and mitigate climate change.
Check Digit Verification of cas no
The CAS Registry Mumber 11126-05-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,1,2 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 11126-05:
(7*1)+(6*1)+(5*1)+(4*2)+(3*6)+(2*0)+(1*5)=49
49 % 10 = 9
So 11126-05-9 is a valid CAS Registry Number.
