3-(Isopropylamino-acetyl)-p-toluolsulfonanilid, also known as acetaminophen or paracetamol, is a widely used over-the-counter analgesic and antipyretic drug. It is an organic compound with the chemical formula C8H9NO2S, consisting of a para-aminophenol group, an acetanilide group, and a p-toluenesulfonamide group. This medication is primarily used to relieve mild to moderate pain, such as headaches, muscle aches, and arthritis, as well as to reduce fever. It works by inhibiting the production of prostaglandins in the central nervous system, which are responsible for pain and fever. Acetaminophen is generally well-tolerated, but it can cause liver damage if taken in excessive amounts, so it is crucial to follow the recommended dosage guidelines.
The CAS Registry Mumber 5322-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,2 and 2 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5322-26: (6*5)+(5*3)+(4*2)+(3*2)+(2*2)+(1*6)=69 69 % 10 = 9 So 5322-26-9 is a valid CAS Registry Number.
