3-(2-isopropyl-5-methyl-phenyl)-propionic acid, also known as ibuprofen, is a widely used nonsteroidal anti-inflammatory drug (NSAID) with analgesic, antipyretic, and anti-inflammatory properties. It is derived from the propionic acid class of NSAIDs and is chemically represented by the formula C13H18O2. Ibuprofen works by inhibiting the cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins that cause inflammation, pain, and fever. It is commonly used to relieve mild to moderate pain, reduce fever, and manage inflammation associated with conditions such as arthritis, menstrual cramps, and other musculoskeletal disorders.
The CAS Registry Mumber 4427-52-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 7 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4427-52: (6*4)+(5*4)+(4*2)+(3*7)+(2*5)+(1*2)=85 85 % 10 = 5 So 4427-52-5 is a valid CAS Registry Number.
