Urea, cyclohexyltrimethyl-, also known as 1-cyclohexyl-1,1,3,3-tetramethylurea or Cymel 303, is a white crystalline compound with the chemical formula C11H22N2O. It is a derivative of urea, where a cyclohexyl group replaces one of the hydrogen atoms on the nitrogen atom. This chemical is widely used as a phase-transfer catalyst in various organic reactions, particularly in the synthesis of pharmaceuticals and agrochemicals. It is also employed as a corrosion inhibitor in the oil and gas industry, as well as a stabilizer in the production of polyurethane foams. Due to its unique properties, urea, cyclohexyltrimethyl- plays a significant role in various industrial applications, making it an important chemical in the modern chemical industry.
The CAS Registry Mumber 33034-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 33034-71: (7*3)+(6*3)+(5*0)+(4*3)+(3*4)+(2*7)+(1*1)=78 78 % 10 = 8 So 33034-71-8 is a valid CAS Registry Number.
