475563-22-5 Usage
General Description
Biperiden hydrochloride is a chemical compound that belongs to the class of anticholinergic drugs. It is commonly used to treat symptoms of Parkinson's disease, such as tremors, stiffness, and muscle spasms. By blocking the action of acetylcholine in the brain, biperiden hydrochloride helps to alleviate these symptoms and improve motor function in patients with Parkinson's disease. It is also sometimes used as an adjunct treatment for certain other conditions, such as drug-induced extrapyramidal symptoms and dystonia. However, biperiden hydrochloride can cause side effects such as dry mouth, blurred vision, constipation, and urinary retention, so it should be used with caution and under the guidance of a healthcare professional.
Check Digit Verification of cas no
The CAS Registry Mumber 475563-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,5,6 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 475563-22:
(8*4)+(7*7)+(6*5)+(5*5)+(4*6)+(3*3)+(2*2)+(1*2)=175
175 % 10 = 5
So 475563-22-5 is a valid CAS Registry Number.

Hydrochloric acid method for the new preparation method (by machine translation)
-
, (2017/04/18)
The present invention provides a kind of hydrochloric acid I for the new preparation method, which belongs to the technical field of pharmaceutical and chemical synthesis, it solves the problem of large-scale preparation-oriented method for the hydrochloric acid, the product made in accordance with the latest European Pharmacopoeia standards. The method in order to 5 - vinyl - 2 - norbornene the alkene is starting material selectively oxidize to make the appearance of the key 5 - acetyl norbornene, then the Mannich reaction, from the outside to the isomerization salt forming reaction, Grignard reaction and salt forming reaction to obtain the product. The invention raw materials are easy, low cost, simple operation, mild reaction conditions, has good industrial application value. (by machine translation)
