The chemical compound "(1E,5Z,9Z,12R)-9-acetoxymethyl-1,5-dimethyl-12-(5-methyl-1-methylene-hex-4-enyl)-cyclotetradeca-1,5,9-triene" is a complex organic molecule with a unique structure. It features a cyclotetradeca (14-carbon) ring with three double bonds in the 1, 5, and 9 positions, indicating a triene. The molecule also contains two methyl groups at the 1 and 5 positions, and a 9-acetoxymethyl group, which is an acetate ester attached to the 9-carbon. Additionally, the 12-carbon is substituted with a 5-methyl-1-methylene-hex-4-enyl group, which is a branched chain containing a methyl group and a methylene group, with a double bond at the 4-position. The stereochemistry is specified by the E, Z, and R descriptors, indicating the orientation of the double bonds and the chirality at the 12-carbon. (1E,5Z,9Z,12R)-9-acetoxymethyl-1,5-dimethyl-12-(5-methyl-1-methylene-hex-4-enyl)-cyclotetradeca-1,5,9-triene is likely to be found in the realm of natural products or as a synthetic intermediate in organic chemistry, given its intricate structure.
The CAS Registry Mumber 74269-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,6 and 9 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 74269-54: (7*7)+(6*4)+(5*2)+(4*6)+(3*9)+(2*5)+(1*4)=148 148 % 10 = 8 So 74269-54-8 is a valid CAS Registry Number.
