98514-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98514-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,1 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98514-81:
(7*9)+(6*8)+(5*5)+(4*1)+(3*4)+(2*8)+(1*1)=169
169 % 10 = 9
So 98514-81-9 is a valid CAS Registry Number.

Novel Lithium-selective Ionophores bearing an Easily Ionizable Moiety
Kimura, Keiichi,Sakamoto, Hidefumi,Kitazawa, Sadaya,Shono, Toshiyuki
, p. 669 - 670 (1985)
Lipophilic 14-crown-4 derivatives incorporating a nitrophenol substituent are excellent lithium ionophores for proton-driven cation transport, in which extremely high selectivity ratios of lithium over sodium are realized.
