127686-43-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127686-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,8 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127686-43:
(8*1)+(7*2)+(6*7)+(5*6)+(4*8)+(3*6)+(2*4)+(1*3)=155
155 % 10 = 5
So 127686-43-5 is a valid CAS Registry Number.

Polymeric membrane sodium-selective electrodes based on lipophilic calix[4]arene derivatives
Kimura, Keiichi,Miura, Tsutomu,Matsuo, Mitsunori,Shono, Toshiyuki
, p. 1510 - 1513 (1990)
Three kinds of lipophilic calix[4]aryl ester and amide derivatives (1-3) have been designed for Na+-selective polymeric membrane electrodes. The calixarene ionophores have thus proved to be excellent Na+ neutral carriers. Furthermore
