1327-98-6 Usage
Preparation
1,2,4-Trichloro-7-amino-3H-isophenoxazin-3-one?and sodium polysulphide?aqueous solution in the presence of glycerol heating, in 75 ~ 98 ℃ reflux 7 hours, add SODIUM chloride cure completely, then heating, in 103 ~ 104 ℃ reflux 24 hours. This is by thiazine Chloranil and 6 – amino – 3 – methyl – thiophenol zinc salt in Etanol solution to return next condensation and have to (BIOS 1155, 31). In the same way,1,2,4 – trichloro -7- iso-ethoxy-3H-phenothiazine-3-one system color slant blue dye (FIAT 1313,3,243).

Check Digit Verification of cas no
The CAS Registry Mumber 1327-98-6 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, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1327-98:
(6*1)+(5*3)+(4*2)+(3*7)+(2*9)+(1*8)=76
76 % 10 = 6
So 1327-98-6 is a valid CAS Registry Number.
