Chlorcyclizine dihydrochloride is a synthetic antihistamine belonging to the class of piperazine compounds. It was initially developed to treat allergic reactions, such as hay fever or urticaria, due to its ability to inhibit the biological effect of histamine by blocking histamine receptors. This causes a reduction in capillary permeability, relieving symptoms like itching and redness. Recently, it has also been studied for its potential antiviral properties, particularly against the hepatitis C virus. It is also used for alleviating symptoms of the common cold and rhinitic symptoms. Chlorcyclizine dihydrochloride comes under the category of first-generation antihistamines, hence it can cause sedation.

Check Digit Verification of cas no

The CAS Registry Mumber 129-71-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129-71:
(5*1)+(4*2)+(3*9)+(2*7)+(1*1)=55
55 % 10 = 5
So 129-71-5 is a valid CAS Registry Number.
