Phosphorodithioic acid O,O-bis(1-methylethyl)S-[[(1-methylethyl)thio]methyl] ester, also known as fenamiphos, is an organophosphorus compound widely used as an agricultural pesticide. It is a broad-spectrum insecticide and acaricide, effective against a variety of pests, including aphids, mites, and caterpillars. Fenamiphos works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. The chemical structure of fenamiphos consists of a phosphorodithioic acid core with two isopropyl (1-methylethyl) groups and a methylthiomethyl group attached to the sulfur atom. Due to its effectiveness and low mammalian toxicity, fenamiphos is a popular choice for crop protection in various agricultural settings.

2667-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2667-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,6 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.Calculate Digit Verification of CAS Registry Number 2667-52:
(6*2)+(5*6)+(4*6)+(3*7)+(2*5)+(1*2)=99
99 % 10 = 9
So 2667-52-9 is a valid CAS Registry Number.
