The chemical compound "(1R)-O2,O3;O4,O5-diisopropylidene-1-(1H-pyrazol-3-yl)-D-arabinitol" is a complex organic molecule with a unique structure. It features a chiral center at the 1-position, indicated by the (1R) notation, which specifies the configuration of the molecule. The compound contains a pyrazol-3-yl group attached to the 1-position, which is a heterocyclic ring system known for its diverse chemical properties. The diisopropylidene group is a protecting group that shields the hydroxyl groups at the 2,3;4,5-positions, preventing them from reacting in certain chemical processes. (1R)-O2,O3;O4,O5-diisopropylidene-1-(1(2)H-pyrazol-3-yl)-D-arabinitol is a derivative of D-arabinitol, a sugar alcohol, which provides a backbone for the molecule. The combination of these elements results in a molecule with potential applications in various fields, including pharmaceuticals and chemical research, due to its specific stereochemistry and functional groups.
The CAS Registry Mumber 71052-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,5 and 2 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 71052-58: (7*7)+(6*1)+(5*0)+(4*5)+(3*2)+(2*5)+(1*8)=99 99 % 10 = 9 So 71052-58-9 is a valid CAS Registry Number.
