3.3.5.7.7-Pentanitrononan-1.9-dicarbonsaeure, also known as pentanitro-1,9-nonanedione, is a chemical compound characterized by the presence of five nitro groups and two carbonyl groups. It is a highly energetic and potentially explosive substance, derived from the dicarbonyl compound 1,9-nonanedione, which is a nine-carbon ketone with two carbonyl groups at the terminal positions. The addition of five nitro groups to this structure significantly increases its reactivity and sensitivity, making it a compound of interest in the field of explosives and propellants. Due to its hazardous nature, handling and storage of pentanitro-1,9-nonanedione require strict safety measures and expertise in the field of chemical safety.
The CAS Registry Mumber 1642-62-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 2 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1642-62: (6*1)+(5*6)+(4*4)+(3*2)+(2*6)+(1*2)=72 72 % 10 = 2 So 1642-62-2 is a valid CAS Registry Number.
