698-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 698-20-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 698-20:
(5*6)+(4*9)+(3*8)+(2*2)+(1*0)=94
94 % 10 = 4
So 698-20-4 is a valid CAS Registry Number.

Cyclopropanation using flow-generated diazo compounds

Roda, Nuria M.,Tran, Duc N.,Battilocchio, Claudio,Labes, Ricardo,Ingham, Richard J.,Hawkins, Joel M.,Ley, Steven V.

supporting information, p. 2550 - 2554 (2015/11/17)

We have devised a room temperature process for the cyclopropanation of electron-poor olefins using unstabilised diazo compounds, generated under continuous flow conditions. This protocol was applied to a wide range of different diazo species to generate f

Advantageous Syntheses of Diazo Compounds by Oxidation of Hydrazones with Lead Tetraacetate in Basic Environments

Holton, Terrence L.,Shechter, Harold

, p. 4725 - 4729 (2007/10/02)

Varied sensitive diazo compounds 3 are produced efficiently and safely in 3-6 g quantities by oxidation (eq 1) of hydrazones 1 at -78 deg C with lead tetraacetate (2) in triethylamine/chloroform, N-methylmorpholine/dimethylformamide, tetramethylguanidine (8)/dimethylformamide, and tetramethylguanidine/methylene chloride, respectively, upon use of appropriate workup and handling techniques.New and improved nonhazardous procedures have been developed for preparing and handling hydrazones 1 from aldehydes and ketones in reactions with excess hydrazine.
