The chemical compound "(1R)-O2,O3;O4,O5-diisopropylidene-1-[1-(toluene-4-sulfonyl)-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 to the first carbon. This pyrazol-3-yl group is further modified with a toluene-4-sulfonyl moiety, indicating the presence of a sulfonamide functional group. The molecule also includes a diisopropylidene bridge, which connects the second and third, as well as the fourth and fifth, hydroxyl groups of the arabinitol, protecting them from unwanted reactions. (1R)-O2,O3;O4,O5-diisopropylidene-1-[1-(toluene-4-sulfonyl)-1H-pyrazol-3-yl]-D-arabinitol is likely to be used in advanced chemical synthesis or as a potential pharmaceutical intermediate due to its intricate structure and functional groups.
The CAS Registry Mumber 71087-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,8 and 7 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 71087-04: (7*7)+(6*1)+(5*0)+(4*8)+(3*7)+(2*0)+(1*4)=112 112 % 10 = 2 So 71087-04-2 is a valid CAS Registry Number.
