General Description
1-(2,5-Diaminophenylazo)-naphthalene, also known as Fast Orange G, is an organic compound with the chemical formula C16H14N4. It is a synthetic dye commonly used in the textile industry to produce vibrant orange and red colors. 1-(2,5-Diaminophenylazo)-naphthalene is derived from naphthalene and contains a diazo group, which gives it its distinctive color properties. It is also used as an indicator in analytical chemistry and as a fluorescent probe in biological research. However, due to its potential carcinogenicity and environmental impact, efforts are being made to develop safer alternative dyes for industrial applications.Check Digit Verification of cas no
The CAS Registry Mumber 169798-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,7,9 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 169798-42:
(8*1)+(7*6)+(6*9)+(5*7)+(4*9)+(3*8)+(2*4)+(1*2)=209
209 % 10 = 9
So 169798-42-9 is a valid CAS Registry Number.
