4-bromo-2,5,7-trinitro-9H-fluoren-9-one - tetracene (1:1) is a complex organic compound consisting of two distinct molecules, 4-bromo-2,5,7-trinitro-9H-fluoren-9-one and tetracene, combined in a 1:1 ratio. The first molecule, 4-bromo-2,5,7-trinitro-9H-fluoren-9-one, is a derivative of fluorenone with a bromine atom at the 4-position, and three nitro groups at the 2, 5, and 7 positions. Tetracene, on the other hand, is a polycyclic aromatic hydrocarbon with four fused benzene rings. This combination results in a unique chemical entity with potential applications in various fields, such as materials science, organic synthesis, and chemical research. The specific properties and reactivity of 4-bromo-2,5,7-trinitro-9H-fluoren-9-one - tetracene (1:1) are influenced by the presence of both the highly electron-withdrawing nitro groups and the electron-donating bromine atom, as well as the conjugated system of the tetracene molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 991-56-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 991-56:
(5*9)+(4*9)+(3*1)+(2*5)+(1*6)=100
100 % 10 = 0
So 991-56-0 is a valid CAS Registry Number.
