2,4-Dinitro-9-p-toluolsulfonyloxy-fluoren is a complex organic compound with the chemical formula C20H15N3O7S. It is characterized by the presence of two nitro groups (NO2) at the 2nd and 4th carbon positions, a p-toluolsulfonyl group (C7H7SO2) attached to the 9th carbon position, and a hydroxyl group (OH) at the same position. 2,4-Dinitro-9-p-toluolsulfonyloxy-fluoren is a derivative of fluorene, a polycyclic aromatic hydrocarbon, and is known for its potential applications in the synthesis of various pharmaceuticals and chemical intermediates. The p-toluolsulfonyl group provides a protecting function for the hydroxyl group, which can be crucial in certain chemical reactions. The compound's structure and properties make it a valuable component in advanced organic synthesis, particularly in the preparation of complex molecules that require selective protection and deprotection strategies.

1858-90-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1858-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1858-90:
(6*1)+(5*8)+(4*5)+(3*8)+(2*9)+(1*0)=108
108 % 10 = 8
So 1858-90-8 is a valid CAS Registry Number.
