69805-79-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69805-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,0 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 69805-79:
(7*6)+(6*9)+(5*8)+(4*0)+(3*5)+(2*7)+(1*9)=174
174 % 10 = 4
So 69805-79-4 is a valid CAS Registry Number.

N-functionalized benzotriazole-1-carboximidoyl chlorides: Synthetic equivalents for isocyanide dichlorides

Katritzky,Rogovoy,Klein,Insuasty,Vvedensky,Insuasty

, p. 2854 - 2857 (2001)

Readily prepared N-functionalized benzotriazole-1-carboximidoyl chlorides are proposed as stable and novel isocyanide dichloride synthetic equivalents. Subsequent condensations of these new intermediates afford polysubstituted guanidines, S-aryl isothiour

METHOD OF CONVERTING CARBON DIOXIDE INTO CARBONYL COMPOUNDS

-

Page/Page column 14, (2019/05/02)

The present invention provides a method for fixing carbon dioxide gas as a carbonyl compound represented by formula (3) as depicted by Figure 1 and comprising, purging of carbon dioxide in a solution of a nucleophile represented by the formula (1) in presence of a solvent at a temperature ranging from -40 Degree Celsius to 35 Degree Celsius, followed by adding a reagent at temperature ranging from -40 degree to 35 degree and thereafter adding another nucleophile represented by the formula (2) to obtain carbonyl compound represented by formula (3). The present invention can be advantageously used to obtain commercially important carbonyl compounds and clean unwanted carbon dioxide gas from the atmosphere and industrial effluents.

Facile direct synthesis of unsymmetrical ureas from N-Alloc-, N-Cbz-, and N-Boc-protected amines using DABAL-Me3

Kang, Soosung,Kim, Hee-Kwon

, p. 4036 - 4046 (2018/06/13)

A practical synthetic method for the direct synthesis of unsymmetrically substituted ureas from N-Alloc-, N-Cbz-, and N-Boc-protected amines is described. In this study, efficient direct conversion of the Alloc-, Cbz-, and Boc-carbamate compounds to ureas was achieved in the presence of DABAL-Me3, an air stable and easily handled reagent. Using this reaction method, both protected aromatic and aliphatic amines were successfully transformed into various trisubstituted and tetrasubstituted ureas with high yields without side product. Our findings offer promising guidelines for direct preparation of useful ureas from N-Alloc-, N-Cbz-, and N-Boc-carbamates.
