Check Digit Verification of cas no

The CAS Registry Mumber 55153-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55153-64:
(7*5)+(6*5)+(5*1)+(4*5)+(3*3)+(2*6)+(1*4)=115
115 % 10 = 5
So 55153-64-5 is a valid CAS Registry Number.

Synthesis and antibacterial in vitro activity of novel analogues of nematophin

Himmler, Thomas,Pirro, Franz,Schmeer, Norbert

, p. 2045 - 2050 (1998)

The synthesis and in vitro antibacterial activity of new derivatives and analogues of nematophin are described. It was shown that the unsubstituted amide NH-group is essential for bioactivity. Alkyl- or aryl-substitution at the 1-position results in a distinct increase of antibacterial activity. Addition of protein (blood or serum) to the culture media reduces the inhibitory activity on bacteria.

Iodide/H2O2 catalyzed intramolecular oxidative amination for the synthesis of 3,20-pyrrolidinyl spirooxindoles

Gao, Yu-Ting,Jin, Xiao-Yang,Liu, Qi,Liu, An-Di,Cheng, Liang,Wang, Dong,Liu, Li

supporting information, (2018/09/12)

An ammonium iodide/hydrogen peroxide-mediated intramolecular oxidative amination of 3-aminoalkyl-2-oxindoles was achieved, affording the corresponding 3,20-pyrrolidinyl spirooxindoles and their 6- or 7-membered analogous in moderate to high yields. This metal-free procedure features very mild reaction conditions, non-toxicity and easily handled hydrogen peroxide as a clean oxidant.
