(1S,4R,5R)-5-((E)-2-Methoxy-vinyl)-5-methyl-6-methylene-bicyclo[2.2.1]hept-2-ene is a complex organic compound with a unique molecular structure. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the 1S, 4R, and 5R configurations indicating the arrangement of atoms in three-dimensional space. The compound features a bicyclo[2.2.1]hept-2-ene core, which is a type of bicyclic hydrocarbon with two carbon rings. One of the rings is a cyclopropane, a three-carbon ring, and the other is a cyclohexene, a six-carbon ring with a double bond. The molecule also includes a 2-methoxyvinyl group, which is a vinyl group (a carbon-carbon double bond) with a methoxy (-OCH3) substituent, and a 5-methyl group, indicating a methyl (-CH3) group attached to the fifth carbon. The 6-methylene group refers to a methylene (-CH2-) group at the sixth position. (1S,4R,5R)-5-((E)-2-Methoxy-vinyl)-5-methyl-6-methylene-bicyclo[2.2.1]hept-2-ene is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a component in various chemical reactions.
The CAS Registry Mumber 77228-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,2 and 8 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 77228-98: (7*7)+(6*7)+(5*2)+(4*2)+(3*8)+(2*9)+(1*8)=159 159 % 10 = 9 So 77228-98-9 is a valid CAS Registry Number.
