"O,O-diethyl O-(4-nitrophenyl) phosphorothioate - O,O-dimethyl O-(4-nitrophenyl) phosphorothioate (1:1)" refers to a mixture of two organophosphorus compounds in a 1:1 ratio. The first compound, O,O-diethyl O-(4-nitrophenyl) phosphorothioate, is characterized by two ethyl groups attached to a phosphorus atom, which is also connected to a 4-nitrophenyl group and a sulfur atom. The second compound, O,O-dimethyl O-(4-nitrophenyl) phosphorothioate, has two methyl groups instead of ethyl groups. These chemicals are known for their pesticidal properties, particularly as a type of organophosphate insecticide. They work by inhibiting the enzyme acetylcholinesterase in insects, leading to a buildup of acetylcholine and subsequent overstimulation of the nervous system. This mixture is used in agriculture to control a variety of pests, but due to their toxicity and potential environmental impact, their use is strictly regulated in many countries.

8003-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 8003-98-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 8003-98:
(6*8)+(5*0)+(4*0)+(3*3)+(2*9)+(1*8)=83
83 % 10 = 3
So 8003-98-3 is a valid CAS Registry Number.
