Check Digit Verification of cas no
The CAS Registry Mumber 6408-50-0 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, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6408-50:
(6*6)+(5*4)+(4*0)+(3*8)+(2*5)+(1*0)=90
90 % 10 = 0
So 6408-50-0 is a valid CAS Registry Number.

Environmentally friendly preparation method of solvent blue 63 dye
-
Paragraph 0009; 0010; 0011; 0012, (2017/08/29)
The invention relates to an environmentally friendly preparation method of a solvent blue 63 dye. The preparation method comprises (a) adding m-toluidine into a reaction container, orderly adding 1-methylamino-4-bromoanthraquinone, an alkali metal hydroxide and a copper salt into the reaction container along with stirring, heating the mixture to 100 to 130 DEG C and carrying out a reaction process for 4 to 7 hours until a terminal point, wherein a mass ratio of 1-methylamino-4-bromoanthraquinone, m-toluidine, alkali metal hydroxide to copper salt is 6: 12-16: 3-4: 0.04-0.08, and (b) cooling the product obtained by the step a to 60-70 DEG C, then adding methanol into the product, carrying out separation, carrying out stirring, carrying out cooling to 30-50 DEG C, and carrying out filtration, washing and drying. The method has the advantages of high reaction purity, few side reactions, short reaction time, obvious crystallization, washing easiness and less washing wastewater.
