39123-65-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39123-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39123-65:
(7*3)+(6*9)+(5*1)+(4*2)+(3*3)+(2*6)+(1*5)=114
114 % 10 = 4
So 39123-65-4 is a valid CAS Registry Number.

Novel synthesis of 3-substituted 2-thiohydantoins via aza-Wittig reaction on poly(ethylene glycol)

Xiang, Fengying,Zhang, Shoubo,Lu, Cuifen,Chen, Zuxing,Yang, Guichun

, p. 953 - 960 (2008)

A novel method for the liquid-phase combinatorial synthesis of 3-substituted-2-thiohydantoin has been developed by using poly (ethylene glycol)-supported isothiocyanate. The PEG-supported isothiocyanate was obtained from the reaction of PEG with bromoacet

HETEROCYCLIC INTEGRIN AGONISTS

Paragraph 0219; 0220, (2018/07/29)

The present invention provides polycyclic oxothioxoimidazolidines, dioxoimidazolines, oxothioxooxazolidines, dioxooxazolidines, and related compounds, which are useful as integrin agonists. Methods for the treatment of integrin-mediated diseases such as cancer are also described.

Preparation of 2'-13c-l-histidine starting from 13c-thiocyanate: Synthetic access to any site-directed stable isotope enriched l-histidine

Talab, Sarra,Taha, Kamal Khalifa,Lugtenburg, Johan

, p. 1023 - 1033 (2014/02/14)

1-Benzyl-2-(methylthio)-imidazole-5-ketone is obtained in a few simple steps starting from thiocyanate and glycine amide (glycin). Subsequent treatment with diethyl phosphorocyanidate and functional group manipulations gives 1-benzyl-5-chloromethylimidazolium chloride. This compound is converted under mild O'Donnell conditions into the corresponding L-histidine derivative. After deprotection L-histidine is obtained in good yield and 99% enantiomeric excess. 2'-13C-L-Histidine has been obtained via this new scheme with high (99%) 13C incorporation starting with commercially available 13C- thiocyanate. This synthetic scheme allows access to any isotopomer of L-histidine and many other biologically important imidazole derivatives.
