1-p-Tolyl-3-(2,2,2-trichloro-1-p-tolylamino-ethyl)-urea, also known as DCPMU, is a chemical compound with the molecular formula C16H15Cl3N2O. It is a derivative of urea, featuring a p-tolyl group (a methyl group attached to a phenyl ring) at the 1-position and a 2,2,2-trichloro-1-p-tolylamino-ethyl group at the 3-position. 1-p-Tolyl-3-(2,2,2-trichloro-1-p-tolylamino-ethyl)-urea is primarily used as a herbicide, specifically for controlling broadleaf and grassy weeds in various crops. DCPMU works by inhibiting the enzyme acetolactate synthase, which is essential for the synthesis of branched-chain amino acids in plants, ultimately leading to the cessation of plant growth. Due to its effectiveness and selectivity, it is widely used in agriculture to protect crops from weed competition.
The CAS Registry Mumber 68550-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 0 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 68550-09: (7*6)+(6*8)+(5*5)+(4*5)+(3*0)+(2*0)+(1*9)=144 144 % 10 = 4 So 68550-09-4 is a valid CAS Registry Number.
