Tris-o-(methoxyphenyl)-2-acetyl-3,4,5-triphenylcyclopentadienylide is a complex organic compound with the molecular formula C42H33O5. It is characterized by a cyclopentadienyl core, which is a five-membered ring with alternating double bonds, and three phenyl groups attached to the 3, 4, and 5 positions. Each of the three methoxyphenyl groups is attached to the cyclopentadienyl ring at the ortho position (adjacent to the carbonyl group). The 2-position of the cyclopentadienyl ring is acetylated, meaning it has an acetyl group (a two-carbon fragment derived from acetic acid) attached to it. tris-o-(methoxyphenyl)-2-acetyl-3,4,5-triphenylcyclopentadienylide is likely to be used in advanced organic synthesis or as a precursor in the production of other complex molecules, given its intricate structure.

Check Digit Verification of cas no

The CAS Registry Mumber 86268-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,6 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 86268-53:
(7*8)+(6*6)+(5*2)+(4*6)+(3*8)+(2*5)+(1*3)=163
163 % 10 = 3
So 86268-53-3 is a valid CAS Registry Number.

TRITOLYLARSONIUM AND TRIS(METHOXYPHENYL)ARSONIUM YLIDES THE EFFECTS OF ortho-SUBSTITUENTS IN TRIARYLARSONIUM GROUPS ON THE PROPERTIES OF YLIDES

Harris, Gordon S.,Lloyd, Douglas,MacDonald, William A.,Gosney, Ian

, p. 297 - 304 (2007/10/02)

A number of tritolylarsonium and tris(methoxyphenyl)arsonium cyclopentadienylides and other ylides have been prepared and their properties (basicity, NMR spectra, reactions with aldehydes and nitrosobenzene, acetylation, and methanolysis) have been investigated.Substituents in the m- or p-positions of triarylarsonium groups have little effect on properties, but o-substituents result in markedly lower reactivity and lower basicity, and these ylides were also more difficult to prepare.NMR spectra gave indication of crowding in some of these o-substituted ylides.The effects of the o-substituents are discussed. p-Methyl- and p-methoxy-substituents increased the proportion of anil to ketoxime formed in reactions with nitrosobenzene, but the o-methoxy analogue gave only ketoxime.
