57808-65-8 Usage
Description
Closantel is a kind of synthetic anti parasitic agent which is actively against liver fluke, bloodsucking nematodes and larval stages of some arthropods in sheep and cattle. Its mechanism of action is through decoupling the mitochondrial oxidative phosphorylation, thus inhibiting the production of ATP. Therefore, it inhibit their energy generation of the parasite, causing their death. It is mainly used for the treatment and prevention of several infections caused by many kinds of parasites such as Fasciola hepatica, Fasciola gigantica, Haemonchus concortus, Haemonchus placei, Bunostomum phlebotomum, Oesophagostomum radiatum and Strongyloides papillosus in cattle and sheep.

Check Digit Verification of cas no
The CAS Registry Mumber 57808-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,0 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57808-65:
(7*5)+(6*7)+(5*8)+(4*0)+(3*8)+(2*6)+(1*5)=158
158 % 10 = 8
So 57808-65-8 is a valid CAS Registry Number.

Paragraph 0033-0036, (2019/07/04)
The invention discloses a method for preparing [...], which belongs to the chemical pharmaceutical intermediates preparation method technical field, the use of P-acetonitrile, O-nitro-P-chlorotoluene and 2 - hydroxy - 3, 5 - diiodosalicylic benzoic acid as the raw material, by condensation reaction, the reduction reaction and re-condensation reaction, then in the sodium hydroxide solution the salifiable preparation 2 - (trifluoromethyl) pyridine - 3 - formaldehyde. The method of the invention, adopting a relatively friendly reducing agent to replace the iron powder such as iron and waste water and the like to avoid the emission of pollutants, and simplifying the post-treatment, the improved process simple and safe operation, mild reaction conditions, the product yield is relatively high, less "wastes", has high industrial value.
