99552-37-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99552-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,5 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99552-37:
(7*9)+(6*9)+(5*5)+(4*5)+(3*2)+(2*3)+(1*7)=181
181 % 10 = 1
So 99552-37-1 is a valid CAS Registry Number.

Synthesis and drug complexation studies with ss-cyclodextrins fluorinated on the primary face
Diakur,Zuo,Wiebe
, p. 209 - 223 (2007/10/03)
Three fluorinated β-cyclodextrin derivatives, namely 5, 9 and 12, were prepared with the hope that the fluorine reporter group may assist in direct evaluation of the complexation properties of these potential drug carriers. Two of the synthesized derivatives, the previously reported monofluoro-β-cyclodextrin 9 and the novel trifluoroethylthio-β-cyclodextrin 12, displayed reasonable aqueous solubility and thus were suitable for drug-cyclodextrin complexation studies. Preliminary NMR results (1H and 19F) on the host-guest complex formation of both of these cyclodextrin derivatives with amantidine, a therapeutic agent employed in the treatment of Influenza A infections, are also presented.
