The chemical compound "(1R)-1-[1-(2,4-dinitro-phenyl)-1H-pyrazol-3-yl]-O2,O3;O4,O5-diisopropylidene-O1-methanesulfonyl-D-arabinitol" is a complex organic molecule with a unique structure. It features a pyrazole ring attached to a 2,4-dinitrophenyl group, which is a common moiety in many biologically active compounds. The molecule also includes a D-arabinitol core, which is a sugar alcohol, and is modified with a methanesulfonyl group at the O1 position. Additionally, the molecule has a diisopropylidene protecting group at the O2, O3; O4, O5 positions, which is often used in organic synthesis to protect hydroxyl groups from unwanted reactions. (1R)-1-[1-(2,4-dinitro-phenyl)-1H-pyrazol-3-yl]-O2,O3;O4,O5-diisopropylidene-O1-methanesulfonyl-D-arabinitol is likely to be of interest in the field of medicinal chemistry, potentially as a precursor to other compounds or as a molecule with biological activity itself.
The CAS Registry Mumber 71052-61-4 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, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 71052-61: (7*7)+(6*1)+(5*0)+(4*5)+(3*2)+(2*6)+(1*1)=94 94 % 10 = 4 So 71052-61-4 is a valid CAS Registry Number.
