103754-13-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103754-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,5 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103754-13:
(8*1)+(7*0)+(6*3)+(5*7)+(4*5)+(3*4)+(2*1)+(1*3)=98
98 % 10 = 8
So 103754-13-8 is a valid CAS Registry Number.

Synthesis of Some Novel 2-Substitutedbenzyl-(4)7-phenyl-1H-benzo[d]imidazoles in Mild Conditions as Potent Anti-Tyrosinase and Antioxidant Agents

Do?an, ?nci S.,?zel, Arzu,Birinci, Zeynep,Barut, Burak,Sellitepe, Hasan E.,Kahveci, Bahittin

, p. 881 - 888 (2016/11/09)

Novel 2-substitutedbenzyl-4(7)-phenyl-1H-benzo[d]imidazole compounds were synthesized and characterized. Although 2a and 2b were reported previously in the literature, 11 compounds were synthesized (nine of them were newly synthesized) and the tyrosinase inhibitory effects and antioxidant activities of these compounds were studied for the first time. All of the synthesized compounds displayed certain inhibitory effects on tyrosinase, with IC50 values ranging from 37.86 ± 0.24 to 75.81 ± 2.49 μM. Among the compounds, 2j exhibited similar tyrosinase inhibitory effect (IC50 = 37.86 ± 0.24 μM) to the positive control, kojic acid (IC50 = 21.93 ± 0.11 μM). Kinetic studies revealed it to act as non-competitive tyrosinase inhibitor with a Ki value of 50.2 μM. The antioxidant activities of the compounds were investigated by using in vitro antioxidant assays, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). All of these results indicated that the compounds might have potential application as tyrosinase inhibitors.

Microwave-assisted synthesis of some 5(6)-nitro-1H-benzimidazoles and their hydrazide derivatives

Yilmaz, Fatih,Mentese, Emre,Karaali, Nesrin,Kahveci, Bahittin

, p. 265 - 271 (2013/07/27)

A series of 5(6)-nitro-1H-benzimidazole and their hydrazide derivatives were synthesized starting from iminoester hydrochloride and 4-nitro-o- phenylenediamine under microwave irradiation. The structure of all synthesized compounds was confirmed by IR, s

Microwave-assisted synthesis of some new benzylidenamino compounds and potentiometric determination of their pKa

Mentese, Emre,Islamoglu, Fatih,Kahveci, Bahittin

, p. 907 - 913 (2013/09/23)

A growing body of literature has shown the effectiveness of using microwaves in chemical reactions. The aim of this study is to demonstrate a rapid and highly efficient synthesis of some new benzylidenamino compounds (4a-f) via microwave heating using a m
