The chemical compound in question is a complex organic molecule with a chiral center, denoted as (1S)-D-O2,O4;O3,O5-(R,R)-dibenzylidene-1-(2,6-bis-benzyloxy-pyridin-3-yl)-ribitol. (1S)-D-O2,O4;O3,O5-(R,R)-dibenzylidene-1-(2,6-bis-benzyloxy-pyridin-3-yl)-ribitol features a ribitol core, which is a sugar alcohol with five hydroxyl groups. The ribitol is modified with a 2,6-bis-benzyloxy-pyridin-3-yl group attached to the first carbon, indicating the presence of a pyridine ring with two benzyloxy substituents at the 2 and 6 positions and a 3-yl group. Additionally, the molecule has a dibenzylidene bridge connecting the 2nd and 4th hydroxyl groups, as well as the 3rd and 5th hydroxyl groups, which contributes to its rigid structure. The (R,R) configuration at the dibenzylidene bridge indicates that both asymmetric carbons in this part of the molecule have the R configuration. (1S)-D-O2,O4;O3,O5-(R,R)-dibenzylidene-1-(2,6-bis-benzyloxy-pyridin-3-yl)-ribitol is likely to be a synthetic intermediate or a complex molecule with potential applications in pharmaceuticals or materials science, given its intricate structure and multiple chiral centers.
The CAS Registry Mumber 29266-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 29266-89: (7*2)+(6*9)+(5*2)+(4*6)+(3*6)+(2*8)+(1*9)=145 145 % 10 = 5 So 29266-89-5 is a valid CAS Registry Number.
