1-Naphthalenesulfonic acid, 8-cyano-, also known as 8-Cyanonaphthalene-1-sulfonic acid, is an organic compound with the chemical formula C11H7NO2S. It is a derivative of naphthalene, a polycyclic aromatic hydrocarbon, with a sulfonic acid group at the 1-position and a cyano group at the 8-position. 1-Naphthalenesulfonic acid, 8-cyano- is characterized by its yellow crystalline appearance and is soluble in water. It is primarily used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes. Due to its chemical structure, it exhibits properties such as acidity and reactivity towards nucleophiles, which are crucial for its applications in the dye industry.
The CAS Registry Mumber 83-20-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 83-20: (4*8)+(3*3)+(2*2)+(1*0)=45 45 % 10 = 5 So 83-20-5 is a valid CAS Registry Number.
