68140-20-5 Usage
General Description
1H,1H,2H,2H-perfluoroalkyl-1-thiols are a type of chemical compound that contain a perfluoroalkyl chain attached to a sulfur atom. They are commonly used in various industrial and commercial applications due to their unique properties, including their strong resistance to heat, chemicals, and environmental degradation. These compounds are often used as surface modifiers to create water and oil repellent coatings on various materials such as fabrics, paper, and metal surfaces. They are also used in the production of specialty chemicals, fluorochemicals, and as components in various consumer products. However, there is growing concern about the potential environmental and health impacts of these chemicals, including their persistence in the environment and bioaccumulation in living organisms. As a result, some regulatory measures have been put in place to restrict the use of certain perfluoroalkyl compounds in order to mitigate their potential risks.
Check Digit Verification of cas no
The CAS Registry Mumber 68140-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68140-20:
(7*6)+(6*8)+(5*1)+(4*4)+(3*0)+(2*2)+(1*0)=115
115 % 10 = 5
So 68140-20-5 is a valid CAS Registry Number.
