1-Deuteroindene is a deuterated analog of indene, an aromatic hydrocarbon with the molecular formula C9H8. In 1-deuteroindene, one of the hydrogen atoms in indene is replaced by a deuterium atom, resulting in a molecular formula of C9H7D. Deuterium, also known as heavy hydrogen, has an atomic mass of approximately 2, which is twice that of a regular hydrogen atom. This substitution can affect the chemical and physical properties of the molecule, such as its boiling point, reactivity, and spectroscopic behavior. 1-Deuteroindene is primarily used in chemical research and as a reference material in spectroscopic studies, allowing for the investigation of isotope effects and the development of more accurate analytical techniques.
The CAS Registry Mumber 933-61-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 3 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 933-61: (5*9)+(4*3)+(3*3)+(2*6)+(1*1)=79 79 % 10 = 9 So 933-61-9 is a valid CAS Registry Number.
