138441-76-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138441-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,4 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138441-76:
(8*1)+(7*3)+(6*8)+(5*4)+(4*4)+(3*1)+(2*7)+(1*6)=136
136 % 10 = 6
So 138441-76-6 is a valid CAS Registry Number.

Sulfonates-PMMA nanoparticles conjugates: A versatile system for multimodal application

Monasterolo, Claudio,Ballestri, Marco,Sotgiu, Giovanna,Guerrini, Andrea,Dambruoso, Paolo,Pistone, Assunta,Varchi, Greta,Cesare, Michelandrea De,Beretta, Giovanni Luca,Zunino, Franco,Benfenati, Valentina,Sparnacci, Katia,Laus, Michele

We report herein the viability of a novel nanoparticles (NPs) conjugated system, namely the attachment, based on ionic and hydrophobic interactions, of different sulfonated organic salts to positively charged poly(methylmethacrylate) (PMMA)-based core-shell nanoparticles (EA0) having an high density of ammonium groups on their shells. In this context three different applications of the sulfonates?EA0 systems have been described. In detail, their ability as cytotoxic drugs and pro-drugs carriers was evaluated in vitro on NCI-H460 cell line and in vivo against human ovarian carcinoma IGROV-1 cells. Besides, 8-hydroxypyrene-1,3,6-trisulfonic acid, trisodium salt (HPTS) was chosen for NPs loading, and its internalization as bioimaging probe was evaluated on Hep G2 cells. Overall, the available data support the interest for these PMMA NPs?sulfonates systems as a promising formulation for theranostic applications. In vivo biological data strongly support the potential value of these core-shell NPs as delivery system for negatively charged drugs or biologically active molecules. Additionally, we have demonstrated the ability of these PMMA core-shell nanoparticles to act as efficient carriers of fluorophores. In principle, thanks to the high PMMA NPs external charge density, sequential and very easy post-loading of different sulfonates is achievable, thus allowing the preparation of nanocarriers either with bi-modal drug delivery behaviour or as theranostic systems.
