Check Digit Verification of cas no

The CAS Registry Mumber 108816-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,1 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108816-99:
(8*1)+(7*0)+(6*8)+(5*8)+(4*1)+(3*6)+(2*9)+(1*9)=145
145 % 10 = 5
So 108816-99-5 is a valid CAS Registry Number.

Synthesis of new macrocyclic lactones and their extraction study

Bayrakci,Ertul

experimental part, p. 1384 - 1388 (2009/09/06)

New macrocyclic lactones were synthesized by reaction of 3-bromo-5-(5-tert-butyl-2-hydroxybenzyl)biphenyl-4-ol with appropriate polyethylene glycol-based dicarboxylic acid dichlorides, and their complexes with Mg(ClO4)2·6H2O, Pb(SCN) 2, NaClO4·H2O, and KClO4 were prepared. The macrocyclic ligands were evaluated as extractants in the transfer of Li+, Na+, K+, Cu2+, Ni 2+, and Hg2+ picrates from aqueous to organic phase.
