(2R,3R)-2-[(Z)-4-(1-Methoxy-1-methyl-ethoxy)-but-1-enyl]-3-((2Z,5Z)-octa-2,5-dienyl)-oxirane is a complex organic compound characterized by its chiral centers and double bonds. It features a 2,3-epoxy structure, with the 2-position occupied by a (Z)-4-(1-methoxy-1-methyl-ethoxy)but-1-enyl group and the 3-position substituted with a (2Z,5Z)-octa-2,5-dienyl group. The compound's stereochemistry is defined by the (2R,3R) configuration, indicating that both chiral centers have the R configuration. The presence of Z double bonds in the substituents suggests that the double bonds are in the same plane, with the highest priority groups on the same side of the double bond. (2R,3R)-2-[(Z)-4-(1-Methoxy-1-methyl-ethoxy)-but-1-enyl]-3-((2Z,5Z)-octa-2,5-dienyl)-oxirane is likely to be found in the realm of natural products or as an intermediate in organic synthesis, given its intricate structure and functional groups.
The CAS Registry Mumber 89408-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,0 and 8 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 89408-91: (7*8)+(6*9)+(5*4)+(4*0)+(3*8)+(2*9)+(1*1)=173 173 % 10 = 3 So 89408-91-3 is a valid CAS Registry Number.
