189330-23-2 Usage
General Description
5-(Difluoromethyl)thiophene-2-carboxylic acid is a chemical compound consisting of a thiophene ring with a carboxylic acid group at position 2 and a difluoromethyl group at position 5. It is often used as a building block in the synthesis of various pharmaceutical compounds and agrochemicals. The difluoromethyl group can enhance the biological activity and metabolic stability of the resulting molecules, making it a valuable tool for drug discovery and development. Additionally, the thiophene core is known for its diverse pharmacological properties, including anti-inflammatory, anticancer, and antimicrobial activities. As a result, 5-(difluoromethyl)thiophene-2-carboxylic acid is an important intermediate in the pharmaceutical and agrochemical industries.
Check Digit Verification of cas no
The CAS Registry Mumber 189330-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,3 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189330-23:
(8*1)+(7*8)+(6*9)+(5*3)+(4*3)+(3*0)+(2*2)+(1*3)=152
152 % 10 = 2
So 189330-23-2 is a valid CAS Registry Number.
