71907-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71907-55-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,0 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71907-55:
(7*7)+(6*1)+(5*9)+(4*0)+(3*7)+(2*5)+(1*5)=136
136 % 10 = 6
So 71907-55-6 is a valid CAS Registry Number.

Macrocyclic amides as ionophores for lead-selective membrane electrodes
Malinowska,Wroblewski,Ostaszewski,Jurczak
, p. 701 - 706 (2007/10/03)
A series of ionophores based on diaza 18-crown-6 units possessing amide and sulfonamide functions were prepared. Their complexing properties were investigated insolvent polymeric membrane electrodes. The influence of the structure of ligands, prepared on
