(+/-)-(2E/2Z)-3-Methyl-5-(2,6,6-trimethylcyclohex-2-en-1-yl)penta-2,4-dien-saeure-ethylester is a complex organic compound with a molecular formula of C16H24O2. It is a chiral molecule, indicated by the (+/-) notation, meaning it can exist in two enantiomeric forms. The compound features a 3-methylpentadienyl group and a 2,6,6-trimethylcyclohex-2-en-1-yl group, which are connected through a double bond in the 2,4-diene system. The ester functional group is formed by the attachment of an ethyl group to the carboxylic acid. (+/-)-(2E/2Z)-3-Methyl-5-(2,6,6-trimethylcyclohex-2-en-1-yl)penta-2,4-dien-saeure-ethylester is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a component in specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 3548-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3548-81:
(6*3)+(5*5)+(4*4)+(3*8)+(2*8)+(1*1)=100
100 % 10 = 0
So 3548-81-0 is a valid CAS Registry Number.

Optisch aktive 4,5-Epoxy-4,5-dihydro-α-ionone und Synthese der stereoisomeren 4,5:4',5'-Diepoxy-4,5,4',5'-tetrahydro-ε,ε-carotine und der sterische Verlauf ihrer Hydrolyse

, p. 816 - 834 (1986)

We prove that epoxidation with peracid of α-ionone, contrary to a recently published statement, predominantly leads to the cis-epoxide.Acid hydrolysis affords a single 4,5-glycol whose structure, established by an X-ray analysis, shows that oxirane opening occured with inversion at the least substituted position (C(4)).Stable cis- and trans-epoxides are prepared by epoxidation of the C15-phosphonates derived from α-ionone.Both the racemic and optically active form are used for the synthesis of the 4,5:4',5'-diepoxy-4,5,4',5'-tetrahydro-ε,ε-carotenes having the following configuration in the end goups: meso-cis/cis, meso-trans/trans, rac-cis/trans, rac- and (6R,6'R)-cis/cis, rac- and (6R,6'R)-trans/trans, rac- and (6R,6'R)-cis/trans, and (6R,6'R)-cis/ε.Acid hydrolysis of the cis/cis-epoxycarotenoids under relatively strong conditions occurs again with inversion at C(4)/C(4') in case of the cis/cis-epoxycarotenoids, but at C(5)/C(5') in case of the trans/trans-epoxycarotenoids.An independent synthesis of this 4,5,4',5'-tetrahydro-ε,ε-carotene-4,5,4',5'-tetrol is presented.The irregular results of the oxirane hydrolysis are explained by assumption of neighbouring effects of the lateral chain. 400-MHz-1H-NMR data are given for each of the stereoisomeric sets.In the visible range of the CD spectra, the (6R,6R')-epoxycarotenoids compared with (6R,6R')-ε,ε-carotene exhibit an inversion of the Cotton effects.
