73776-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73776-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,7 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73776-05:
(7*7)+(6*3)+(5*7)+(4*7)+(3*6)+(2*0)+(1*5)=153
153 % 10 = 3
So 73776-05-3 is a valid CAS Registry Number.

Synthesis, structural characterization and metal inclusion properties of 18-, 20- and 22-membered oxaazacyclophanes and oxaazacalix[4]arene analogues: Macrocyclic amine and schiff base receptors with variable NxO y donor sets

Moreno-Corral, Ramon,Hoepfl, Herbert,MacHi-Lara, Lorena,Lara, Karen O.

, p. 2148 - 2162 (2011/05/09)

A series of oxaazacyclophanes and oxaazacalix[4]arene analogues with 18-, 20- and 22-membered rings have been synthesized from diamine and dialdehyde building blocks and structurally characterized by spectroscopic methods. One diamine precursor and four macrocycles have additionally been analysed by single-crystal X-ray diffraction. Two of the oxaazacalix[4]arene analogues were employed for metal ion complexation studies based on UV/Vis absorption spectroscopy, showing both compounds to be able to form complexes with Cu 2+ and Zn2+.
