748799-88-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 748799-88-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,8,7,9 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 748799-88:
(8*7)+(7*4)+(6*8)+(5*7)+(4*9)+(3*9)+(2*8)+(1*8)=254
254 % 10 = 4
So 748799-88-4 is a valid CAS Registry Number.

A convenient protocol for the synthesis of ligands from a 4-methyl-3,5-diacylaminophenyl platform

Pickaert, Guillaume,Cesario, Michele,Ziessel, Raymond

, p. 5335 - 5341 (2007/10/03)

The synthesis of stable and highly organized phenanthroline, terpyridine, and pyridino-oxazoline ligands bearing one or two 4-methyl-3,5-diacylaminophenyl modules equipped with two lateral dialkoxyphenyl groups has been performed using EDC·HCl and DMAP reagents in the final coupling reaction. Evidently, in the final ligands and in the solid state intermolecular hydrogen bonding maintains the coherence of the tridimensional structure as clearly evidenced by FT-IR and X-ray diffraction spectroscopy in the cases of the methoxy ligands. The supramolecular packing is also maintained by additional π-π stacking interactions.
