Cis,cis-3,5-octadiene is an organic compound with the molecular formula C8H14. It is a diene, which means it contains two carbon-carbon double bonds. The "cis,cis" notation indicates that both double bonds are in the same relative position, with the substituents on each double bond being on the same side of the molecule. This geometric isomerism results in different physical and chemical properties compared to other isomers, such as the trans,trans or cis,trans configurations. Cis,cis-3,5-octadiene is a colorless liquid with a strong, pungent odor and is used in the synthesis of various chemicals, including fragrances and pharmaceuticals. It is also a precursor in the production of vitamin A and other carotenoids. Due to its reactive nature, it is sensitive to light, heat, and oxygen, requiring careful handling and storage.

7348-80-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7348-80-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7348-80:
(6*7)+(5*3)+(4*4)+(3*8)+(2*8)+(1*0)=113
113 % 10 = 3
So 7348-80-3 is a valid CAS Registry Number.

Regio- and Stereo-specific Reduction of Conjugated and Non-conjugated Triple Bonds by Activated Zinc Powder

Aerssens, Marc H. P. J.,Brandsma, Lambert

, p. 735 - 736 (1984)

Regio- as well as stereo-specific reductions of a wide variety of acetylenic derivatives have been carried out in absolute ethanol with zinc powder activated with 1,2-dibromoethane, and with zinc powder activated successively with dibromoethane and copper(I) bromide, the first reagent being less powerful and more selective than the second one.

A Quick Procedure for the Partial Reduction of Triple Bonds

Aerssens, M.H.P.J.,Heiden, R. van der,Heus, M.,Brandsma, L.

, p. 3421 - 3425 (2007/10/02)

Regio- as well as stereospecific cis-reductions of a wide variety of acetylenic derivatives can be carried out in absolute ethanol with zinc powder activated with 1,2-dibromoethane and with zinc power treated successively with dibromoethane and lithium bromocuprate, the first reagent being less powerful and more selective than the second one.
