Purification Methods
Purify the dye by precipitating the free acid from aqueous solution using concentrated HCl, then wash it and extract it with EtOH in a Soxhlet extractor. Evaporation of the EtOH leaves the purified acid which is converted to the sodium salt.
Check Digit Verification of cas no
The CAS Registry Mumber 3564-26-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3564-26:
(6*3)+(5*5)+(4*6)+(3*4)+(2*2)+(1*6)=89
89 % 10 = 9
So 3564-26-9 is a valid CAS Registry Number.
