"O,O-diethyl O,O-dimethyl thiodiphosphate" is a chemical compound with the formula (C2H5O)2P(S)OP(S)(OC2H5)2. It is an organophosphorus compound that belongs to the class of thiodiphosphates. O,O-diethyl O,O-dimethyl thiodiphosphate is known for its potential use as a pesticide, specifically as an insecticide and acaricide. It works by inhibiting the enzyme acetylcholinesterase, which is crucial for the proper functioning of the nervous system in insects. This inhibition leads to the overstimulation of the nervous system, ultimately causing paralysis and death in the target pests. The compound is also recognized for its potential toxicity and environmental impact, highlighting the need for careful handling and application in agricultural settings.

Check Digit Verification of cas no

The CAS Registry Mumber 470-85-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 470-85:
(5*4)+(4*7)+(3*0)+(2*8)+(1*5)=69
69 % 10 = 9
So 470-85-9 is a valid CAS Registry Number.
