(R)-6-Isopropenyl-9-methyl-1,4-dioxa-spiro[4.5]decane is a complex organic compound characterized by its unique molecular structure. It features a spiro[4.5]decane core, which is a type of spiro compound consisting of two rings sharing a common carbon atom. The compound is further defined by the presence of a 1,4-dioxane ring, which contributes to its cyclic ether structure. The (R)-6-Isopropenyl group indicates the presence of an isopropenyl moiety (a three-carbon chain with a double bond) at the 6th position, and the 9-methyl group signifies a methyl group at the 9th position. This chiral molecule, with its specific stereochemistry, is important in the field of organic chemistry, particularly in the synthesis of complex molecules and the study of stereoselective reactions.
The CAS Registry Mumber 4643-59-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 3 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4643-59: (6*4)+(5*6)+(4*4)+(3*3)+(2*5)+(1*9)=98 98 % 10 = 8 So 4643-59-8 is a valid CAS Registry Number.
