Methyldichlorodithiophosphates are a class of organophosphorus compounds characterized by the presence of a methyl group, two chlorine atoms, and two dithiophosphoric acid groups. These chemicals are primarily used as pesticides, specifically as insecticides and acaricides, due to their ability to inhibit acetylcholinesterase, an enzyme essential for nerve function in insects. They are effective against a wide range of pests, including mites, aphids, and beetles, and are often used in agriculture to protect crops. However, their use has been associated with environmental and health concerns, leading to restrictions or bans in some regions. Methyldichlorodithiophosphates are also known for their potential to cause harm to non-target organisms and their persistence in the environment, which has prompted ongoing research into safer alternatives.
The CAS Registry Mumber 5390-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 0 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5390-60: (6*5)+(5*3)+(4*9)+(3*0)+(2*6)+(1*0)=93 93 % 10 = 3 So 5390-60-3 is a valid CAS Registry Number.
