1327-77-1 Usage
Preparation
5-(4-Hydroxyanilino)-8-(4-methylanilino)-lnaphthalenesulfonic acid?in the presence of Copper sulfate monohydrate with Sodium polysulfide ethanol solution heating, reflux 50 hours, then add the Sodium nitrite, again boiling 6 hours, steamed out ethanol, in 50 ~ 60 ℃ blowing air make precipitation. This indophenol?is by 8-(P-toluidino)naphthalene-1-sulfonic acid and where did 4-Aminophenol with Sodium hypochlorite oxidation of mixture, then use Sodium hydrosulfide reduction and have to (BIOS 1155, 11-12)Properties and Applications

3Check Digit Verification of cas no
The CAS Registry Mumber 1327-77-1 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 7 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1327-77:
(6*1)+(5*3)+(4*2)+(3*7)+(2*7)+(1*7)=71
71 % 10 = 1
So 1327-77-1 is a valid CAS Registry Number.
