2',4'-Dinitro-4-phenoxy-2-methylmercapto-azobenzol is a complex organic compound with the chemical formula C14H11N3O5S. It is characterized by the presence of two nitro groups (-NO2) at the 2' and 4' positions, a phenoxy group (-C6H5O) attached to the 4 position, and a methylmercapto group (-SCH3) at the 2 position. The azobenzol structure, which consists of two benzene rings connected by a diazenyl (-N=N-) bridge, is a key feature of this molecule. 2',4'-Dinitro-4-phenoxy-2-methylmercapto-azobenzol is known for its potential applications in the field of dyes and pigments, particularly for its ability to produce vibrant colors. It is also of interest in chemical research due to its unique structure and reactivity. However, it is important to note that the compound's properties, such as toxicity and environmental impact, should be carefully considered and studied before any practical applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1657-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1657-76:
(6*1)+(5*6)+(4*5)+(3*7)+(2*7)+(1*6)=97
97 % 10 = 7
So 1657-76-7 is a valid CAS Registry Number.
