28172-18-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28172-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,7 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28172-18:
(7*2)+(6*8)+(5*1)+(4*7)+(3*2)+(2*1)+(1*8)=111
111 % 10 = 1
So 28172-18-1 is a valid CAS Registry Number.

Two step synthesis of a non-symmetric acetylcholinesterase reactivator

Musilek, Kamil,Kuca, Kamil,Dohnal, Vlastimil,Jun, Daniel,Marek, Jan,Koleckar, Vit

, p. 1755 - 1761 (2007)

The newly developed and very promising acetylcholinesterase reactivator (E)-1-(2-hydroxyiminomethylpyridinium)-4-(4-hydroxyiminomethylpyridinium) -but-2-ene dibromide was prepared using two different pathways via a two-step synthesis involving the appropriate (E)-1-(4-bromobut-2-enyl)-2- or 4-hydroxyiminomethyl-pyridinium bromides. Afterwards, purities and yields of the desired product prepared by both routes were compared. Finally, its potency to reactivate several nerve agent-inhibited acetylcholinesterases was tested.

The preparation, in vitro screening and molecular docking of symmetrical bisquaternary cholinesterase inhibitors containing a but-(2E)-en-1,4-diyl connecting linkage

Musilek, Kamil,Pavlikova, Ruzena,Marek, Jan,Komloova, Marketa,Holas, Ondrej,Hrabinova, Martina,Pohanka, Miroslav,Dohnal, Vlastimil,Dolezal, Martin,Gunn-Moore, Frank,Kuca, Kamil

, p. 245 - 253 (2011)

Carbamate inhibitors (e.g. pyridostigmine bromide) are used as a pre-treatment for the prevention of organophosphorus poisoning. They work by blocking the native function of acetylcholinesterases (AChE) and thus protect AChE against irreversible inhibitio

Novel series of bispyridinium compounds bearing a (Z)-but-2-ene linker-Synthesis and evaluation of their reactivation activity against tabun and paraoxon-inhibited acetylcholinesterase

Musilek, Kamil,Holas, Ondrej,Kuca, Kamil,Jun, Daniel,Dohnal, Vlastimil,Opletalova, Veronika,Dolezal, Martin

, p. 3172 - 3176 (2008/02/05)

Six novel AChE reactivators with a (Z)-but-2-ene linker were synthesized using the known synthetic pathways. Their ability to reactivate AChE, which had been previously inhibited by nerve agent tabun or pesticide paraoxon, was tested in vitro and compared
