4891-54-7

Demeton-O-sulfone is a metabolite of the organophosphorus pesticide Demeton, which is used to control various pests in agriculture. It is formed in the environment and within organisms after the application of Demeton, and it is considered to be more persistent and toxic than the parent compound. Demeton-O-sulfone is an organophosphorus compound with the chemical formula C6H15O4PS2, and it is characterized by its ability to inhibit acetylcholinesterase, an enzyme crucial for the proper functioning of the nervous system. This inhibition can lead to a range of adverse effects, including acute toxicity in humans and non-target organisms. Due to its potential risks, the use of Demeton and its related compounds has been restricted or banned in many countries to protect human health and the environment.

4891-54-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4891-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4891-54:
(6*4)+(5*8)+(4*9)+(3*1)+(2*5)+(1*4)=117
117 % 10 = 7
So 4891-54-7 is a valid CAS Registry Number.
