"dl-6aα,7,10,10aα-Tetrahydro-1-hydroxy-6,6-dimethyl-3-pentyl-6H-dibenzo[b,d]pyran-9(8H)-on" is a complex organic compound with a molecular formula of C21H28O3. It is a derivative of dibenzo[b,d]pyran, a type of heterocyclic compound with a fused benzene ring system. This specific compound features a tetrahydro structure, indicating four hydrogen atoms have been added across a double bond, and a hydroxyl group (-OH) attached to the 1-position. The molecule also contains two methyl groups (-CH3) at the 6-position, and a pentyl group (-C5H11) at the 3-position, which contributes to its lipophilic nature. The compound's structure and properties make it a potential candidate for pharmaceutical applications, particularly in the development of drugs targeting the central nervous system. Its stereochemistry is indicated by the "dl" prefix, suggesting a racemic mixture of both the (+) and (-) enantiomers.

Check Digit Verification of cas no

The CAS Registry Mumber 6616-69-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,1 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6616-69:
(6*6)+(5*6)+(4*1)+(3*6)+(2*6)+(1*9)=109
109 % 10 = 9
So 6616-69-9 is a valid CAS Registry Number.

The synthesis of some 11-substituted tetrahydrocannabinol metabolites

ApSimon, John W.,Collier, T. Lee,Guiver, Michael D.

, p. 2804 - 2809 (2007/10/02)

9-Bromo-11-oxo-hexahydrocannabinol (5) was prepared from the ketocannabinoid 3b via the epoxysulfone 4.The dehydrobromination of the bromoaldehyde 5 could be controlled to give either the thermodinamically more stable Δ8-aldehyde 2c, or the Δ9-aldehyde 1c by an intramolecularly assisted elimination.Reduction of the unsaturated aldehydes gave the allylic alcohol metabolites 2a and 1a, respectively.
