(3R,6aα,10bα)-Dodecahydro-3,4aβ,7,10aβ-tetramethyl-3α-vinyl-1H-naphtho[2,1-b]pyran-7β-carboxylic acid methyl ester is a complex organic compound with a molecular formula of C19H28O3. It is a derivative of naphthopyran, a heterocyclic compound consisting of a naphthalene ring fused to a pyran ring. The structure of (3R,6aα,10bα)-Dodecahydro-3,4aβ,7,10aβ-tetramethyl-3α-vinyl-1H-naphtho[2,1-b]pyran-7β-carboxylic acid methyl ester is characterized by a dodecahedral carbon skeleton, with four methyl groups attached at different positions, and a vinyl group at the 3α position. The carboxylic acid group is located at the 7β position, and it is esterified with a methyl group, making it a methyl ester. (3R,6aα,10bα)-Dodecahydro-3,4aβ,7,10aβ-tetramethyl-3α-vinyl-1H-naphtho[2,1-b]pyran-7β-carboxylic acid methyl ester is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of pharmaceuticals or other complex organic molecules, given its intricate structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 56687-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,8 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56687-75:
(7*5)+(6*6)+(5*6)+(4*8)+(3*7)+(2*7)+(1*5)=173
173 % 10 = 3
So 56687-75-3 is a valid CAS Registry Number.

RESIN ACIDS OF PINUS RESINOSA NEEDLES

Zinkel, Duane F.,Clarke, Wilbur B.

, p. 1267 - 1272 (1985)

Key Word Index - Pinus resinosa; Pinus nigra; Pinaceae; needles; labdane diterpenes; hybrids. - The principal resin acids in the needles of Pinus resinosa are the labdane diterpenes, the new 8,13-epoxy-14-labden-19-oic acid (epimanoyl oxide acid), 8,13β-epoxy-14-labden-19-oic acid (manoyl oxide acid), 8(17),E-12,14-labdatrien-19-oic acid (communic acid) and 15-oxo-8(17)-labden-19-oic acid (imbricataloic acid).A survey of needles from representative populations of P. resinosa showed a limited variability in resin acid composition consistent with the uniformityof other traits.The composition of needle resin acids for putative P. nigra x resinosa hybrids strongly suggests the improbability of P. resinosa as the pollen parent.
