Benzoylmethylen-tris-(2-cyan-ethyl)-phosphoran, also known as BMTP, is a chemical compound with the molecular formula C16H14N3O2P. It is a colorless, crystalline solid that is soluble in organic solvents. BMTP is a potent organophosphorus compound, which is known for its insecticidal properties. It works by inhibiting the enzyme acetylcholinesterase in the nervous system of insects, leading to their paralysis and death. Due to its high toxicity, BMTP is used in a controlled manner for agricultural and pest control applications. It is important to handle BMTP with care due to its potential hazards, including acute toxicity to humans and the environment.
The CAS Registry Mumber 1439-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1439-40: (6*1)+(5*4)+(4*3)+(3*9)+(2*4)+(1*0)=73 73 % 10 = 3 So 1439-40-3 is a valid CAS Registry Number.
