Although its use as an explosive is not recommended due to safety concerns, 1-(2,4-dinitrophenyl)-2-undecylidenehydrazine has been used as an explosive in the past. Its explosive properties make it a potential candidate for applications in the explosives industry, but it is crucial to handle this chemical with extreme caution and follow proper safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 2121-91-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2121-91:
(6*2)+(5*1)+(4*2)+(3*1)+(2*9)+(1*1)=47
47 % 10 = 7
So 2121-91-7 is a valid CAS Registry Number.

Selective reduction of esters to aldehydes under the catalysis of well-defined NHC-iron complexes

On a direct course to the aldehyde: Hydrosilylation catalyzed by a well-defined N-heterocyclic-carbene-iron complex under UV irradiation enabled the selective reduction of esters to aldehydes (see scheme; Bn=benzyl, Mes=mesityl). The low catalyst loading and very mild reaction conditions make this chemoselective transformation a promising alternative to the reduction of esters with diisobutylaluminum hydride. Copyright
