6,9,10-Trimethylundeca-3,5,9-trien-2-one is a complex organic compound with the molecular formula C14H22O. It is a conjugated dienone, which means it contains two carbon-carbon double bonds separated by a single bond. The compound is characterized by the presence of three methyl groups (CH3) at the 6th, 9th, and 10th carbon atoms, and a ketone group (C=O) at the 2nd carbon atom. This structure gives the molecule unique chemical properties and reactivity. It is an important intermediate in the synthesis of various natural products and pharmaceuticals, and is also used in the preparation of fragrances and flavorings. Due to its complex structure, it is typically synthesized through multi-step organic reactions, and its properties can be further modified through various chemical transformations.

645-68-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 645-68-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 645-68:
(5*6)+(4*4)+(3*5)+(2*6)+(1*8)=81
81 % 10 = 1
So 645-68-1 is a valid CAS Registry Number.
