The chemical compound "(1S)-O1-acetyl-O2,O3;O4,O5-diisopropylidene-1-(3-phenyl-3H-[1,2,3]triazol-4-yl)-D-arabinitol" is a complex organic molecule with a unique structure. It features a D-arabinitol core, which is a sugar alcohol, with an acetyl group attached to the O1 position. The molecule also has a diisopropylidene group bridging the O2, O3; O4, O5 positions, which protects the hydroxyl groups and adds stability. The most distinctive part of the molecule is the 3-phenyl-3H-[1,2,3]triazol-4-yl group attached to the 1-position, which introduces a phenyl ring and a triazole heterocycle, contributing to the molecule's reactivity and potential applications in various chemical and pharmaceutical contexts. (1S)-O1-acetyl-O2,O3;O4,O5-diisopropylidene-1-(3-phenyl-3H-[1,2,3]triazol-4-yl)-D-arabinitol is characterized by its stereochemistry, with the "1S" notation indicating the specific spatial arrangement of the molecule around the chiral center at the 1-position.
The CAS Registry Mumber 59401-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,0 and 1 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 59401-78: (7*5)+(6*9)+(5*4)+(4*0)+(3*1)+(2*7)+(1*8)=134 134 % 10 = 4 So 59401-78-4 is a valid CAS Registry Number.
