3347-31-7 Usage
General Description
O,S-diethyl methylphosphonodithioate, also known as Demeton-S, is a highly toxic organophosphate insecticide and acaricide. This chemical compound is used to control a variety of pests in agriculture, horticulture, and domestic settings. It works by inhibiting the enzyme acetylcholinesterase, leading to excess accumulation of the neurotransmitter acetylcholine in the nervous system, which ultimately causes paralysis and death in insects and mites. However, O,S-diethyl methylphosphonodithioate is also highly toxic to humans and animals, and exposure can lead to symptoms such as nausea, vomiting, diarrhea, respiratory distress, and even death. Due to its high toxicity and potential for harm, it is important to handle and use O,S-diethyl methylphosphonodithioate with extreme caution, following all safety protocols and regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 3347-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3347-31:
(6*3)+(5*3)+(4*4)+(3*7)+(2*3)+(1*1)=77
77 % 10 = 7
So 3347-31-7 is a valid CAS Registry Number.
