5,6-dimethylhept-5-en-2-one is an organic compound with the molecular formula C9H16O. It is a colorless liquid with a strong, fruity odor, and it is commonly used as a flavoring agent in the food and beverage industry. This chemical is a ketone derivative, featuring a carbonyl group (C=O) at the 2nd position and a double bond between the 5th and 6th carbon atoms in a heptane chain. The presence of two methyl groups at the 5th and 6th positions contributes to its unique structure and properties. 5,6-dimethylhept-5-en-2-one is synthesized through various chemical reactions and can be found in trace amounts in natural sources such as fruits and flowers. Its applications extend beyond flavoring, as it is also used in perfumery and as a chemical intermediate in the synthesis of other compounds.

687-68-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 687-68-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 687-68:
(5*6)+(4*8)+(3*7)+(2*6)+(1*8)=103
103 % 10 = 3
So 687-68-3 is a valid CAS Registry Number.

Rerouting and Improving Dauc-8-en-11-ol Synthase from Streptomyces venezuelae to a High Yielding Biocatalyst

Lauterbach, Lukas,Hou, Anwei,Dickschat, Jeroen S.

supporting information, p. 7923 - 7929 (2021/04/21)

The dauc-8-en-11-ol synthase from Streptomyces venezuelae was investigated for its catalytic activity towards alternative terpene precursors, specifically designed to enable new cyclisation pathways. Exchange of aromatic amino acid residues at the enzyme surface by site-directed mutagenesis led to a 4-fold increase of the yield in preparative scale incubations, which likely results from an increased enzyme stability instead of improved enzyme kinetics.
