β-[4-(2-acetamidoethyl)-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 a racemic mixture of two enantiomers, S(+)-Ibuprofen and R(-)-Ibuprofen, with the S(+) enantiomer being the more active form. Ibuprofen works by inhibiting the cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins, leading to reduced inflammation, pain, and fever. It is commonly used to treat conditions such as headaches, menstrual cramps, dental pain, and musculoskeletal disorders. The chemical structure of Ibuprofen consists of a propionic acid backbone with a phenyl ring substituted at the 4-position with a 2-acetamidoethyl group, making it a member of the arylpropionic acid class of NSAIDs.
The CAS Registry Mumber 61629-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,2 and 9 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 61629-94: (7*6)+(6*1)+(5*6)+(4*2)+(3*9)+(2*9)+(1*4)=135 135 % 10 = 5 So 61629-94-5 is a valid CAS Registry Number.
