871894-87-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 871894-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,8,9 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 871894-87:
(8*8)+(7*7)+(6*1)+(5*8)+(4*9)+(3*4)+(2*8)+(1*7)=230
230 % 10 = 0
So 871894-87-0 is a valid CAS Registry Number.

Synthesis and Energetic Properties of 4-Diazo-2,6-dinitrophenol and 6-Diazo-3-hydroxy-2,4-dinitrophenol

Klap?tke, Thomas M.,Preimesser, Andreas,Stierstorfer, J?rg

, p. 4311 - 4315 (2015/07/27)

4-Amino-3,5-dinitroaniline (3) was synthesized by fluorine/amine exchange of 4-fluoro-3,5-dinitroaniline in ethanol. 4-Diazo-2,6-dinitrophenol (Iso-DDNP, 4) was obtained after nitration in HNO3 (100%) and acetic anhydrid. 4-Amino-2,3,5-trinitrophenol (7) was obtained by nitration of N-(4-acetoxyphenyl)acetamide and deprotection of the amine. Further nitration resulted in 6-diazo-3-hydroxy-2,4-dinitrophenol (8). The thermal stability and sensitivity of 4 and 8 toward impact and friction was compared to commercially used DDNP (2-diazo-4,6-dinitrophenol). All target compounds were characterized by single-crystal X-ray diffraction, NMR and elemental analysis and DSC. The sensitivities were determined by BAM methods (drophammer and friction tester). The heats of formation were calculated by using CBS-4M electronic enthalpies and the atomization method. Various detonation parameters such as detonation velocity and pressure were computed by using the EXPLO5 computer code V6.01. The very sensitive diazophenol derivatives diazo-2,6-dinitrophenol and 6-diazo-3-hydroxy-2,4-dinitrophenol could be synthesized by nitration reactions. They are promising alternatives to the commercially used sensitizer DDNP (2-diazo-4,6-dinitrophenol).
