91671-94-2 Usage
Presence of sodium salts
The reaction takes place in the presence of sodium salts, which help to stabilize the chemical structure and facilitate the coupling process.Unique color properties
The coupling of 2,7-naphthalenedisulfonic acid with diazotized 2-amino-4,6-dinitrophenol results in the formation of a complex molecule with unique color properties, making it suitable for a wide range of applications in the manufacturing and textile industries.Check Digit Verification of cas no
The CAS Registry Mumber 91671-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.Calculate Digit Verification of CAS Registry Number 91671-94:
(7*9)+(6*1)+(5*6)+(4*7)+(3*1)+(2*9)+(1*4)=152
152 % 10 = 2
So 91671-94-2 is a valid CAS Registry Number.
