14762-74-4 Usage
General Description
Carbon-13C is a stable isotope of carbon that contains one additional neutron in its nucleus, compared to the more common carbon-12. It is often used in nuclear magnetic resonance (NMR) spectroscopy to study the structures of organic compounds, as the presence of the extra neutron gives it a slightly different magnetic resonance frequency. This allows for more detailed analysis of molecular structures and chemical bonding. Carbon-13C is also used in environmental and metabolic studies, as it can be used to trace the movement and transformation of carbon in various biological and chemical processes. Additionally, carbon-13C is utilized in research related to climate change, as it can provide insight into the carbon cycle and carbon sources and sinks in the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 14762-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,6 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14762-74:
(7*1)+(6*4)+(5*7)+(4*6)+(3*2)+(2*7)+(1*4)=114
114 % 10 = 4
So 14762-74-4 is a valid CAS Registry Number.

Electron Paramagnetic Resonance Study of the Reactivity toward Carbon Monoxide and Oxygen of O- Ions Adsorbed on Silica-supported Molybdenum Catalysts
Gonzalez-Elipe, Agustin R.,Louis, Catherine,Che, Michel

Using the e.p.r. technique, the reaction at 77 K of an O- radical, formed by N2O adsorption on reduced MoO3/SiO2 samples, with CO or 13CO was followed, and possible to detect a CO2- radical (g1=2.0029, g2=2.0016, g3=1.9974, A1=199 G, A2=240 G, A3=207 G) which was stable at room temperature.This species reacted with O2 at 77 K to give rise to a radical of the type (O2COO)- (g1=2.0486, g2=2.0078, g3=2.0026, A1C=OG, A2C=4.8 G, A3C=6 G, A3O1=104 G, A3O11=40 G).At 150 K, it disappeared irreversibly, generating an O2- radical (g1=2.0175, g2=2.0097, g3=2.0040, A3O1=80 G, A3O11=70 G) similar to that formed by direct adsorption of oxygen on reduced MoO3/SiO2.
