"Anti-7-norbornenol-exo,exo-5,6-d2" is a deuterated chemical compound, specifically a derivative of 7-norbornenol, with two deuterium atoms (D) incorporated into its structure. The term "anti" refers to the relative stereochemistry of the molecule, indicating that the hydroxyl group (-OH) and the hydrogen atoms on the exo,exo-5,6 positions are on opposite sides of the molecule. Deuterium is a stable isotope of hydrogen, and its incorporation can be used for various purposes, such as enhancing the stability of the molecule, facilitating spectroscopic analysis, or studying the effects of isotopic substitution on chemical reactions. anti-7-norbornenol-exo,exo-5,6-d2 is often used in research and development, particularly in the fields of organic chemistry and materials science, to understand the behavior of molecules under different conditions and to develop new synthetic strategies.
The CAS Registry Mumber 3391-04-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 1 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3391-04: (6*3)+(5*3)+(4*9)+(3*1)+(2*0)+(1*4)=76 76 % 10 = 6 So 3391-04-6 is a valid CAS Registry Number.
