210688-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 210688-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,6,8 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 210688-98:
(8*2)+(7*1)+(6*0)+(5*6)+(4*8)+(3*8)+(2*9)+(1*8)=135
135 % 10 = 5
So 210688-98-5 is a valid CAS Registry Number.

Synthesis, characterization and structures of 2-(3,5-dimethylpyrazol-1-yl) ethylseleno derivatives and their probable glutathione peroxidase (GPx) like activity

Hodage, Ananda S.,Phadnis, Prasad P.,Wadawale, Amey,Priyadarsini,Jain, Vimal K.

, p. 2992 - 2998 (2011/06/16)

A series of 2-(3,5-dimethylpyrazol-1-yl)ethylseleno derivatives has been synthesized. The glutathione peroxidase like catalytic activity of these compounds has been studied in a model system, in which reduction of hydrogen peroxide with dithiothreitol (DTTred), in the presence of an organoselenium compound was investigated by 1H NMR spectroscopy. All these compounds exhibit GPx like catalytic activities and the catalytic reaction proceeds through a selenoxide intermediate, identified by 77Se{ 1H} NMR spectroscopy.

An efficient organocatalyzed interconversion of silyl ethers to tosylates using DBU and p-toluenesulfonyl fluoride

Gembus, Vincent,Marsais, Francis,Levacher, Vincent

scheme or table, p. 1463 - 1466 (2009/04/07)

A mild and efficient interconversion from silyl ethers to sulfonates esters is reported with good yields. This silyl-sulfonyl exchange proceeds readily in acetonitrile at room temperature in the presence of p-toluenesulfonyl fluoride and a catalytic amount of 1,8-diazabicyclo[5.4.0]undec-7ene (DBU). This method can be used with trimethysilyl (TMS), triethylsilyl (TES) and tert-butyldimethylsilyl (TBDMS) ethers. Georg Thieme Verlag Stuttgart.
