(Z)-3-(2-Methoxy-3-methyl-phenyl)-4-methyl-pent-2-enoic acid ethyl ester is a complex organic compound with the molecular formula C16H20O3. It is a derivative of pent-2-enoic acid, featuring a 2-methoxy-3-methylphenyl group at the 3-position and a 4-methyl group at the 4-position. The molecule is characterized by a Z-configuration, indicating the geometric arrangement of the double bond, with the larger group (2-methoxy-3-methylphenyl) being on the same side of the double bond as the ester group. (Z)-3-(2-Methoxy-3-methyl-phenyl)-4-methyl-pent-2-enoic acid ethyl ester is an ester, with an ethyl group attached to the carboxylic acid moiety, which can influence its solubility and reactivity. It is likely to be found in the realm of synthetic chemistry, potentially used as an intermediate in the synthesis of pharmaceuticals, fragrances, or other specialty chemicals due to its unique structural features.

Check Digit Verification of cas no

The CAS Registry Mumber 82054-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,5 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82054-00:
(7*8)+(6*2)+(5*0)+(4*5)+(3*4)+(2*0)+(1*0)=100
100 % 10 = 0
So 82054-00-0 is a valid CAS Registry Number.

Studies in Terpenoids: Part LV - Synthesis of 5-Hydroxycalamenene, a Phenolic Sesquiterpene from Bazzania tricrenata

Sangaiah, R.,Rao, G. S. Krishna

, p. 13 - 15 (2007/10/02)

Fries rearrangement of o-cresyl isobutyrate (IV) gives the o-hydroxyketone (V).Dehydration and saponification of the Reformatsky reaction product of the methoxyketone (VI) with ethyl bromoacetate affords the unsaturated acid mixture (VII).The saturated aryl methylpentanoic acid (VIII) derived from VII is reacted with ethyllithium to give the ketone (IX).The secondary alcohol (X) obtained from IX is cyclodehydrated and demethylated in one step to give 5-hydroxycalamenene (I) which is produced stepwise also from X via the methoxytetralin (XI) obtained by PPA treatment.
