111689-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111689-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,8 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111689-01:
(8*1)+(7*1)+(6*1)+(5*6)+(4*8)+(3*9)+(2*0)+(1*1)=111
111 % 10 = 1
So 111689-01-1 is a valid CAS Registry Number.

Selective sensing of guanidinium and tetraalkylammonium ions using lipophilic cyclodextrins
Kelly, Patricia M.,Kataky, Ritu,Parker, David,Patti, Antonio F.
, p. 1955 - 1964 (2007/10/03)
A range of lipophilic cyclodextrin derivatives, including 2,6-didodecyl-α and -β-cyclodextrins, and 2,3,6-tri-O-ethyl-β-cyclodextrin, has been examined as ionophores in electrode response studies of the detection of guanidine, alkylated guanidines, creatinine and several tetraalkylammonium ions including choline, acetylcholine and the long chain cationic surfactants CnH(2n+1)NMe3+ (n = 8 -> 16).Interference from Group Ia and IIa cations is minimal for alkylammonium ions (-log kpot > 4 typically) and in certain cases binding of the ion has been further defined by electrospray mass spectrometric and NMR methods.
