5653-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5653-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5653-68:
(6*5)+(5*6)+(4*5)+(3*3)+(2*6)+(1*8)=109
109 % 10 = 9
So 5653-68-9 is a valid CAS Registry Number.

Solvent Dependence of the Monomer–Dimer Equilibrium of Ketone-Substituted Triscatecholate Titanium(IV) Complexes

Kwamen, A. Carel N.,Jenniches, Judith,Oppel, Iris M.,Albrecht, Markus

supporting information, p. 10550 - 10554 (2020/07/24)

Hierarchical helicates based on ketone-substituted titanium(IV)triscatecholates show different monomer-dimer behavior depending on different solvents. The dimerization constants of a whole series of differently alkyl-substituted complexes is analyzed to show that the solvent has a very strong influence on the dimerization. Hereby, effects like solvophobicity/philicity, sterics, electronics of the substituents and weak side-chain—side-chain interactions seem to act in concert.
