869-79-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 869-79-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 869-79:
(5*8)+(4*6)+(3*9)+(2*7)+(1*9)=114
114 % 10 = 4
So 869-79-4 is a valid CAS Registry Number.

Synthesis of urea derivatives from amines and CO2 in the absence of catalyst and solvent

Wu, Chaoyong,Cheng, Haiyang,Liu, Ruixia,Wang, Qiang,Hao, Yufen,Yu, Yancun,Zhao, Fengyu

experimental part, p. 1811 - 1816 (2011/02/22)

Urea derivatives are obtained in mild to good yield from the reactions of primary aliphatic amines with CO2 in the absence of any catalysts, organic solvents or other additives. To optimize reaction conditions, experimental variables including temperature, pressure, the concentration of amine, reaction time etc. were studied. Satisfactory yields were obtained at the optimized conditions that are comparable to the presence of catalyst and solvent. The preliminary investigation of the reaction mechanism showed that alkyl ammonium alkyl carbamate was quickly formed as the intermediate, and then the final product was formed by the intramolecular dehydration.
