(2,5-dimethoxy-4-nitrophenyl) phenyl ketone, also known as DNP, is a chemical compound that is often used in organic synthesis and as a reagent in chemical reactions. It is a yellow crystalline powder with a molecular formula of C14H11NO5 and a molecular weight of 273.24 g/mol. DNP has two methoxy groups and a nitro group attached to a phenyl ring, as well as a carbonyl group attached to another phenyl ring. It is commonly used as a photoinitiator in the production of photopolymers and as a starting material for the synthesis of various organic compounds. Additionally, DNP has been studied for its potential medical applications, particularly in the treatment of neurodegenerative diseases and cancer. However, it is important to handle DNP with caution, as it is highly toxic and can cause irritation to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 68556-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68556-19:
(7*6)+(6*8)+(5*5)+(4*5)+(3*6)+(2*1)+(1*9)=164
164 % 10 = 4
So 68556-19-4 is a valid CAS Registry Number.
