2-(2,4-Dimethyl-phenylamino)-propionic acid methyl ester, also known as mefenamic acid, is a nonsteroidal anti-inflammatory drug (NSAID) with both analgesic and antipyretic properties. It is primarily used to treat mild to moderate pain, such as menstrual cramps, dental pain, and postoperative pain. Mefenamic acid works by inhibiting the cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins, leading to reduced inflammation, pain, and fever. The chemical structure consists of a 2,4-dimethylphenyl group attached to a propionic acid chain, with a methyl ester group at the end. It is available in various forms, including tablets and suspensions, and is generally well-tolerated with few side effects. However, it should be used with caution in patients with a history of kidney or liver disease, as it may exacerbate these conditions.
The CAS Registry Mumber 57836-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,3 and 6 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 57836-82: (7*5)+(6*7)+(5*8)+(4*3)+(3*6)+(2*8)+(1*2)=165 165 % 10 = 5 So 57836-82-5 is a valid CAS Registry Number.
