General Description
2-[(2-amino-5-hydroxy-7-sulpho-1-naphthyl)azo]-5-nitrobenzoic acid, also known as the chemical dye Acid Orange 7, is typically used in the textile industry as an orange dye for coloring fabrics. It is an azo dye, meaning it contains a specific functional group featuring a nitrogen-nitrogen double bond, which gives it its vibrant color. 2-[(2-amino-5-hydroxy-7-sulpho-1-naphthyl)azo]-5-nitrobenzoic acid is also used as an indicator in analytical chemistry, particularly in acid-base titrations, where it changes color depending on the pH of the solution. However,Check Digit Verification of cas no
The CAS Registry Mumber 61827-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,2 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 61827-73:
(7*6)+(6*1)+(5*8)+(4*2)+(3*7)+(2*7)+(1*3)=134
134 % 10 = 4
So 61827-73-4 is a valid CAS Registry Number.
