Check Digit Verification of cas no

The CAS Registry Mumber 128-99-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128-99:
(5*1)+(4*2)+(3*8)+(2*9)+(1*9)=64
64 % 10 = 4
So 128-99-4 is a valid CAS Registry Number.

Active brilliant blue K-GR method for the preparation of intermediates

-

Paragraph 0040-0042, (2017/05/18)

The invention provides a preparation method of a reactive brilliant blue K-GR intermediate. The preparation method comprises following steps: carrying out a condensation reaction between bromamine acid and 2,4-diaminobenzene sulfonic acid or sodium 2,4-diaminobenzene sulfonate with a catalyst system containing a cuprous complex for catalyzing the reaction to obtain the reactive brilliant blue K-GR intermediate (sodium 1-amino-4-((4-amino-3-sulfonylphenyl)amino)-anthraquinone-2-sulfonate). By means of the preparation method of the reactive brilliant blue K-GR intermediate, usage amounts of cuprous chloride and copper powder can be effectively reduced, thereby reducing the content of heavy metals in a dye product, reducing the content of heavy metals in waste water and reducing environmental pollution and production cost. In addition, the preparation method can avoid generation of a hydrolyzed by-product (a purple by-product) of the bromamine acid, can greatly reduce the generation of a debromination by-product, can significantly reduce the generation of a double-condensation substance, can increase yields of the condensation reaction and the dye product and can reduce discharge amount of waste water containing acids and being high in chroma.
