1325-32-2 Usage
Preparation
2-Methoxy-4-nitrobenzenamine diazo, and 4-(8-Hydroxy-6-sulfonaphthalen-2-ylamino)benzoic acid coupling, then use glucose and sodium hydroxide reduction, reoccupy ammonia containing copper sulfate solution of processing.Properties and Applications
blue ash. Soluble in water for dark to gray, not soluble in alcohol. In the dark for the strong sulfuric acid, diluted Gray light purple for a precipitation. Dye with strong hydrochloric acid solution for violet black, precipitation; Add thick sodium hydroxide solution as dark blue, precipitation.

3Check Digit Verification of cas no
The CAS Registry Mumber 1325-32-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1325-32:
(6*1)+(5*3)+(4*2)+(3*5)+(2*3)+(1*2)=52
52 % 10 = 2
So 1325-32-2 is a valid CAS Registry Number.
