The chemical compound "(1R)-O1,O2;O4,O5-diisopropylidene-1-(1H-pyrazol-3-yl)-D-arabinitol" is a complex organic molecule with a unique structure. It features a D-arabinitol core, which is a sugar alcohol, with a pyrazol-3-yl group attached at the 1-position. The molecule is further characterized by the presence of two isopropylidene groups, which are located at the 1,2 and 4,5 positions, respectively. These isopropylidene groups contribute to the molecule's stability and reactivity. The compound's chirality is indicated by the "1R" notation, signifying that the hydroxyl group at the 1-position is on the right side when looking at the molecule in a specific orientation. (1R)-O1,O2;O4,O5-diisopropylidene-1-(1(2)H-pyrazol-3-yl)-D-arabinitol is likely to be of interest in the fields of organic chemistry and medicinal chemistry due to its potential applications in the synthesis of pharmaceuticals or as a chiral building block.
The CAS Registry Mumber 65101-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,0 and 1 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 65101-19: (7*6)+(6*5)+(5*1)+(4*0)+(3*1)+(2*1)+(1*9)=91 91 % 10 = 1 So 65101-19-1 is a valid CAS Registry Number.
