98421-02-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98421-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98421-02:
(7*9)+(6*8)+(5*4)+(4*2)+(3*1)+(2*0)+(1*2)=144
144 % 10 = 4
So 98421-02-4 is a valid CAS Registry Number.

Protein kinases are promising therapeutic targets for cancer therapy. Here, we applied multiple approaches to optimize the potency and selectivity of our reported alloxazine scaffold. Flexible moieties at position 2 of the hetero-tricyclic system were inc

Pteridines. Part LXXXVII. Synthesis and Properties of 8-Substituted 2-Thiolumazines

Huebsch, Walter,Pfleiderer, Wolfgang

, p. 1379 - 1391 (2007/10/02)

Various 8-substituted 2,8-dihydro-2-thioxopteridin-4(3H)-ones (14-21) and 2-(methylthio)pteridin-4(8H)-ones (27-32) have been synthesized by condensation of the appropriate 5-amino-6-(substituted amino)-1,2-dihydro-2-thioxopyrimidin-4(3H)-ones (22-34) and 5-amino-6-(substituted amino)-2-(methylthio)pyrimidin-4(3H)-ones (25,26), respectively, with glyoxal, biacetyl, and benzil.The presence of a quinonoid cross-conjugated ?-electron system makes this type of compounds susceptible to nucleophilic additions in position 7, which laeds to intramolecular (43,45) and intermolecular (44) covalent adducts.The newly synthesized compounds have been characterized by elemental analyses, pKa determinations, 1H-NMR and UV spectra.UV-Spectral changes in dependence of the pH are associated with the most appropriate molecular species including the monocations, neutral forms, covalent adducts, mono- and dianions.
