6409-48-9 Usage

Uses

2,5-Diamino-1,3-benzenedisulfonic Acid is used as a reagent in the synthesis of asymmetric dianilides as intermediates for triphenodioxazine reactive dyes.

Check Digit Verification of cas no

The CAS Registry Mumber 6409-48-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6409-48:
(6*6)+(5*4)+(4*0)+(3*9)+(2*4)+(1*8)=99
99 % 10 = 9
So 6409-48-9 is a valid CAS Registry Number.
