6408-63-5 Usage
Preparation
(C.I. 61710) 1,5-Dichloroanthracene-9,10-dione?(or 1,5-Dinitroanthracene-9,10-dione)and p-Methylaniline condensation, stlfonation, and translated into sodium salt. Note: by 1, 5-and 1, 8-compounds were synthesized mixture of colored light is red to dye ( C.I. 61800). (C.I. 61800) 1,8-Dichloroanthracene-9,10-dione?(or 1,8-Dinitroanthracene-9,10-dione) and p-Methylaniline condensation, stlfonation, and translated into sodium salt. Note: in order to make the product has colored light between C.I. 61710 (slant blue) and C i. 61800 (partial red) between, but will be 1, 5-and 1, 8-compounds on the mixture sulphonated (BIOS 1484 ploidy; FIAT 1313,2,221; FIAT 764-anthraquinone purple).

Check Digit Verification of cas no
The CAS Registry Mumber 6408-63-5 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 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6408-63:
(6*6)+(5*4)+(4*0)+(3*8)+(2*6)+(1*3)=95
95 % 10 = 5
So 6408-63-5 is a valid CAS Registry Number.
