1098-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1098-56-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1098-56:
(6*1)+(5*0)+(4*9)+(3*8)+(2*5)+(1*6)=82
82 % 10 = 2
So 1098-56-2 is a valid CAS Registry Number.

Synthesis and complexing properties of novel crown ethers and thiacrown ethers incorporating new heterocyclic moieties

Bakavoli, Mehdi,Rahimizadeh, Mohammad,Rezaei-Seresht, Esmaeel,Esfahani, Majid Mokaber,Ziaee, Parisa

experimental part, p. 2152 - 2158 (2010/12/18)

The synthesis of some novel crown and thiacrown ethers via the reaction of 2,3-bis(4-hydroxyphenyl) or 2,3-bis(4-mercaptophenyl)quinoxalines and pyridopyridazine with diethylene and triethylene glycol ditosylate is described. The complexing ability of compounds 5b and 5h, as the representatives of both groups of compounds, with alkali and alkali earth metal cations were measured by the solvent extraction method. The results showed that crown ether 5b comparatively had more affinity towards the Mg2+ cation, while thiacrown ether 5h had greater affinity towards the Ca2+ cation.
