(+/-)-(2-Chlor-ethyl)-(1-methyl-3-phenyl-allyl)-ether, also known as chlorpromazine, is a chemical compound with the molecular formula C17H18ClNS. It is a phenothiazine derivative that has been widely used as an antipsychotic medication, primarily for the treatment of schizophrenia and other psychotic disorders. Chlorpromazine exhibits its therapeutic effects by blocking dopamine receptors in the brain, which helps to alleviate symptoms such as hallucinations, delusions, and agitation. The compound is a racemic mixture, meaning it contains equal amounts of both the R and S enantiomers. It is typically administered as a hydrochloride salt and is available in various forms, including tablets, injectable solutions, and suppositories. Chlorpromazine has been in use since the 1950s and remains an important medication in the treatment of various mental health conditions, although its use has been largely replaced by newer, more selective antipsychotic drugs due to its potential for side effects.
The CAS Registry Mumber 3916-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 6 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3916-97: (6*3)+(5*9)+(4*1)+(3*6)+(2*9)+(1*7)=110 110 % 10 = 0 So 3916-97-0 is a valid CAS Registry Number.
