1185115-56-3 Usage
General Description
3,4-Difluoro-benzenesulfonic acid is a chemical compound characterized by the presence of a benzene ring substituted by two fluorine atoms and a sulfonic acid group. The molecular formula of this compound is C6H4F2O3S. It belongs to the class of organic compounds known as fluorobenzenes. Fluorobenzenes are compounds containing a benzene ring where one or more carbon atoms are replaced by a fluorine atom. They are commonly used in a variety of industrial applications, including as intermediates for synthesizing other chemical compounds, solvents, or in some cases, pharmaceuticals. It is known to be corrosive and poses risks upon ingestion, inhalation or dermal contact.
Check Digit Verification of cas no
The CAS Registry Mumber 1185115-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,1,1 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1185115-56:
(9*1)+(8*1)+(7*8)+(6*5)+(5*1)+(4*1)+(3*5)+(2*5)+(1*6)=143
143 % 10 = 3
So 1185115-56-3 is a valid CAS Registry Number.
