2,6-Dinitro-4-(1-butylhexyl)-phenol, also known as DNBP, is a chemical compound with the molecular formula C16H22N2O5. It is an organic compound characterized by the presence of two nitro groups (-NO2) at the 2nd and 6th carbon positions on a phenol ring, and a long alkyl chain (1-butylhexyl) attached to the 4th carbon position. DNBP is a yellowish, crystalline solid with a melting point of approximately 70°C. It is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) materials, providing increased flexibility and durability. However, due to its potential health and environmental concerns, its use has been restricted or banned in some countries.
The CAS Registry Mumber 6465-66-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 5 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6465-66: (6*6)+(5*4)+(4*6)+(3*5)+(2*6)+(1*6)=113 113 % 10 = 3 So 6465-66-3 is a valid CAS Registry Number.
