General Description
(E)-oct-5-en-2-one, also known as 5-octen-2-one, is a chemical compound with the molecular formula C8H14O. It is a colorless liquid with a fruity, mushroom-like odor and is commonly used as a flavoring agent in the food industry. It is found naturally in various fruits and vegetables, as well as in mushrooms and cheese. (E)-oct-5-en-2-one is also used as a fragrance ingredient in perfumes and personal care products due to its pleasant aroma. Additionally, it has applications in the production of polymers and as a precursor in organic synthesis. The compound is considered safe for use in food and is generally recognized as safe (GRAS) by the FDA. However, it should be handled and used with care due to its narcotic properties at high concentrations.
Check Digit Verification of cas no
The CAS Registry Mumber 19093-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,9 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19093-20:
(7*1)+(6*9)+(5*0)+(4*9)+(3*3)+(2*2)+(1*0)=110
110 % 10 = 0
So 19093-20-0 is a valid CAS Registry Number.

A unique procedure to effect a ring-expanding bromoetherification process is described, wherein tetrahydrofurans and tetrahydropyrans are smoothly transformed into 8- and 9-membered bromoethers in a regio- and stereocontrolled manner through the use of BDSB (bromodiethylsulfonium bromopentachloroantimonate). These products resemble the cores of the Laurencia C15 acetogenins. In light of the generality and effectiveness of the approach, this work provides a unique strategy for their laboratory preparation and may implicate a possible biosynthesis pathway.
