The chemical compound "(1S,4aS,7S,7aS)-1-[(2S,3R,4S,5R,6R)-4,5-Diacetoxy-6-acetoxymethyl-3-(4-methoxy-benzoyloxy)-tetrahydro-pyran-2-yloxy]-7-hydroxy-7-methyl-1,4a,5,6,7,7a-hexahydro-cyclopenta[c]pyran-4-carboxylic acid methyl ester" is a complex organic molecule with a highly specific stereochemistry. It features a cyclopenta[c]pyran-4-carboxylic acid core, which is a type of cyclic compound with a five-membered ring fused to a pyran ring. The molecule is adorned with several acetoxy groups, a 4-methoxy-benzoyloxy group, and a methyl ester group, indicating the presence of ester and ether functionalities. The stereochemistry is carefully defined by the 'S' and 'R' configurations at various carbon centers, which are crucial for the molecule's three-dimensional structure and potential biological activity. (1S,4aS,7S,7aS)-1-[(2S,3R,4S,5R,6R)-4,5-Diacetoxy-6-acetoxymethyl-3-(4-methoxy-benzoyloxy)-tetrahydro-pyran-2-yloxy]-7-hydroxy-7-methyl-1,4a,5,6,7,7a-hexahydro-cyclopenta[c]pyran-4-carboxylic acid methyl ester is likely to be of interest in the field of organic chemistry, potentially for its unique structural features or as a precursor in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 88217-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,1 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88217-27:
(7*8)+(6*8)+(5*2)+(4*1)+(3*7)+(2*2)+(1*7)=150
150 % 10 = 0
So 88217-27-0 is a valid CAS Registry Number.

STUDIES ON INDIAN MEDICINAL PLANTS-PART LXXV NISHINDASIDE, A NOVEL IRIDOID GLYCOSIDE FROM VITEX NEGUNDO

Dutta, Pradeep K.,Chowdhury, Uday S.,Chakravarty, Ajit K.,Achari, Basudeb,Pakrashi, Satyesh C.

, p. 3067 - 3072 (1983)

Two new glucosidic iridoids, designated as nishindaside (2a) and negundoside (3a), have been isolated from the leaves of Vitex negundo (Verbenaceae).The absence of a C(3)-C(4) double bond and the presence of an equatorial 3-methoxy group in 2a, the 3-methoxy-3,4-dihydro derivative of agnuside (1a), were established from 1H and 13C NMR analyses, corroborated by mass spectral fragmentation of the hexaacetate (2b).Negundoside (3a) could be concluded to be the 2'-p-hydroxy benzoyl derivative of mussaenosidic acid from the results of alkaline hydrolysis and the shifts in the signals of C-1', C-2' and C-3' in its 13C NMR spectrum.
