Methyl-carbamic acid 3,5-dimethyl-2-nitro-phenyl ester, also known as aldicarb, is a synthetic organophosphorus compound primarily used as an insecticide. It is a white crystalline solid with a chemical formula of C7H8N2O4S. Aldicarb is highly toxic to both insects and mammals, acting as a potent acetylcholinesterase inhibitor, which disrupts the nervous system by preventing the breakdown of the neurotransmitter acetylcholine. This results in overstimulation and paralysis of the nervous system. Due to its high toxicity, aldicarb is classified as a restricted-use pesticide in many countries, and its use is limited to specific applications to minimize exposure and potential harm to humans and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 4654-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4654-48:
(6*4)+(5*6)+(4*5)+(3*4)+(2*4)+(1*8)=102
102 % 10 = 2
So 4654-48-2 is a valid CAS Registry Number.
