Octane-3,4-dione, also known as 3,4-diketone, is an organic compound with the molecular formula C8H14O2. It is a colorless liquid with a pungent odor and is soluble in organic solvents. This diketone is characterized by the presence of two carbonyl groups (C=O) at the 3rd and 4th carbon atoms in an octane chain. Octane-3,4-dione is synthesized through various methods, including the oxidation of 3,4-dihydroxyoctane or the condensation of acetone with butyraldehyde. It is used as a chemical intermediate in the production of various compounds, such as fragrances, pharmaceuticals, and other organic chemicals. Due to its reactivity, it is essential to handle octane-3,4-dione with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

Check Digit Verification of cas no

The CAS Registry Mumber 3457-39-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3457-39:
(6*3)+(5*4)+(4*5)+(3*7)+(2*3)+(1*9)=94
94 % 10 = 4
So 3457-39-4 is a valid CAS Registry Number.
