3-methyl-3,4,5,6,7,8-hexahydro-2H-chromene is a chemical compound belonging to the class of organic compounds, specifically a type of chromane derivative. It is characterized by a benzopyran ring structure, which consists of a benzene ring fused to a pyran ring. The compound has a methyl group attached to the third carbon of the pyran ring, and the molecule is fully saturated, meaning it contains no double bonds. 3-methyl-3,4,5,6,7,8-hexahydro-2H-chromene is an example of a heterocyclic compound, as it contains atoms other than carbon and hydrogen in its ring structure. It is often found in natural products and can be used in the synthesis of various pharmaceuticals and fragrances due to its unique chemical properties and potential biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 16121-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16121-02:
(7*1)+(6*6)+(5*1)+(4*2)+(3*1)+(2*0)+(1*2)=61
61 % 10 = 1
So 16121-02-1 is a valid CAS Registry Number.

ENAMINE CHEMISTRY-XVIII. THE FORMATION OF HEXAHYDROCHROMANE-8a-AMINES BY REDUCTIVE CYCLISATION OF ENAMINES

Carlsson, S.,Lawesson, S.-O.

, p. 3585 - 3590 (2007/10/02)

Enamines (1) derived from cyclohexanone or cyclopentanone are reacted with electrophilic olefins (ethyl acrylate, ethyl 2-methylacrylate, ethyl 2-butenoate) to give the new enamines, 2.When 2 is reacted with LiAlH4, reductive cyclisation takes place giving hexahydrochromane-8a-amines of octahydrocyclopentapyrane-7a-amines, 3, in quantitative yields, 3 is hydrolyzed with dilute aqueous hydrochloric acid to hexahydrochromane-8a-ols of octahydrocyclopentapyrane-7a-ols (4) and reacts also with oxalic acid in refluxing dioxane to form the condensed dihydropyranes, 5.
