68630-38-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68630-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,3 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68630-38:
(7*6)+(6*8)+(5*6)+(4*3)+(3*0)+(2*3)+(1*8)=146
146 % 10 = 6
So 68630-38-6 is a valid CAS Registry Number.

Synthesis, Characterization, and Properties of Pentanitrobenzene C6H(NO2)5

Huber, Tanja,von der Heide, Chantal,Klap?tke, Thomas M.,Krumm, Burkhard

, p. 126 - 132 (2019)

The synthesis of the polynitroaromatic compound pentanitrobenzene was re-examined by modern spectroscopic, structural and physicochemical methods. Originally prepared in 1979, this material could exhibit interesting properties as an oxygen-rich energetic building block. The energies of formation were calculated with the GAUSSIAN program package and the detonation parameters were predicted using the EXPLO5 computer code. The performance data were determined and compared to the common oxidizer ammonium perchlorate. The crystal structure of pentanitrobenzene was determined by X-ray crystallography, and those of 2,3,4,6-tetranitroaniline and styphnic acid (trinitroresorcinol) were re-determined.
