120757-41-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120757-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,7,5 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120757-41:
(8*1)+(7*2)+(6*0)+(5*7)+(4*5)+(3*7)+(2*4)+(1*1)=107
107 % 10 = 7
So 120757-41-7 is a valid CAS Registry Number.

scheme or table, p. 4058 - 4064 (2010/10/02)

The synthesis and characterization of 3-formylchromone (1) and its derivatives 2-24 and evaluation of their potential antiinflammatory activities is reported here. These compounds were characterized by 1H NMR, EI MS, IR, and UV spectroscopic techniques and elemental analysis. The synthesized compounds were evaluated by using various in vitro and in vivo assay models for antiinflammatory activity and their effects were compared with known standard drug such as aspirin and indomethacin. Among all tested compounds, 1, 2, 5, 6, 9, 14, 16-19, 21-23, showed promising antiinflammatory activities. The results and SAR has been discussed in this report. The synthesis and potential antiinflammatory activities of 3-formylchromone (1) and its derivatives 2-24 is reported here. The synthesized compounds were evaluated by using various in vitro and in vivo assay models for antiinflammatory activity.
