186179-54-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186179-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,1,7 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 186179-54:
(8*1)+(7*8)+(6*6)+(5*1)+(4*7)+(3*9)+(2*5)+(1*4)=174
174 % 10 = 4
So 186179-54-4 is a valid CAS Registry Number.

Controlling the orientation of sequential ligands in the self-assembly of binuclear coordination compounds
Albrecht, Markus,Fr?hlich, Roland
, p. 1656 - 1661 (1997)
The sequential ligand 5-H3, which contains one catechol and one aminophenol unit, was prepared in a four-step sequence. The two electronically different binding sites of 5 are able to control the metal-directed self-assembly of binuclear coordi
