Urea, N,N-diethyl-N'-(2-methylphenyl)-N'-nitroso-, also known as N,N-diethyl-N'-(2-methylphenyl)-N'-nitroso-urea or DEN, is an organic compound with the chemical formula C11H16N2O2. It is a derivative of urea, featuring a nitroso group (-NO) attached to the nitrogen atom, and a 2-methylphenyl group connected to the other nitrogen atom. DEN is a yellowish crystalline solid that is soluble in water and organic solvents. It is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its potential toxic and carcinogenic properties, it is important to handle DEN with proper safety precautions and to dispose of it according to environmental regulations.

Check Digit Verification of cas no

The CAS Registry Mumber 97600-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,0 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97600-23:
(7*9)+(6*7)+(5*6)+(4*0)+(3*0)+(2*2)+(1*3)=142
142 % 10 = 2
So 97600-23-2 is a valid CAS Registry Number.

STUDIES ON THE CONFORMATION OF 1-ARYL-1-NITROSOUREAS AND RELATED COMPOUNDS

Tanno, Masayuki,Sueyoshi, Shoko

, p. 1353 - 1359 (2007/10/02)

The carbon-13 nuclear magnetic resonance spectra of 1-aryl-3,3-dialkyl-1-nitrosoureas and related compounds were measured at about -40 degC, and their chemical shifts were assigned.The conformations of the N-nitroso compounds having the 1-aryl-1-nitrosoureido group were established through comparison with N-alkyl-N-nitrosoanilines, and the decomposition mechanism of 1-aryl-3,3-dialkyl-1-nitrosoureas is discussed on the basis of the results.Keywords - 1-aryl-3,3-dialkyl-1-nitrosourea; 1-aryl-1-nitrosourea; N-nitrosourea; N-nitrosoacetanilide; N-nitrosoaniline; triazene; nitrosyl radicals; E-Z conformation; (13)C-NMR
