9-Carbamoyl-octadecansaeure, also known as 9-carbamoyl-octadecanoic acid, is a chemical compound with the molecular formula C19H37NO3. It is a derivative of octadecanoic acid, where the carboxylic acid group (-COOH) is replaced by a carbamoyl group (-CONH2). This modification results in a zwitterionic compound, which means it has both a positive and a negative charge at different sites within the molecule. The compound is characterized by a long hydrocarbon chain of 18 carbon atoms, with the carbamoyl group attached to the 9th carbon. It is a white crystalline solid and is used in various applications, including the synthesis of surfactants, pharmaceuticals, and other organic compounds. Due to its unique structure, 9-carbamoyl-octadecansaeure exhibits properties that differ from those of its parent acid, such as improved solubility in water and potential applications in the development of new materials with specific biological activities.
The CAS Registry Mumber 4165-00-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 5 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4165-00: (6*4)+(5*1)+(4*6)+(3*5)+(2*0)+(1*0)=68 68 % 10 = 8 So 4165-00-8 is a valid CAS Registry Number.
