12768-78-4 Usage
Description
ERIO GREEN B, with the CAS# 12768-78-4, is an organic dye and water-soluble pollutant that is primarily used in the textile industry. It is characterized by its variegated dark green powder form and its unique color properties, which include a blue light green shade when dissolved in water and a green shade when dissolved in ethanol. When it comes into contact with strong sulfuric acid, it turns yellow brown, and upon dilution, it becomes yellow. ERIO GREEN B is known for its high dye migration and good permeability, making it suitable for dyeing dark wool fabrics.
Uses
Used in Textile Industry:
ERIO GREEN B is used as a dye for wool and silk dyeing and printing. It is particularly suitable for dyeing dark wool fabrics due to its high dye migration and good permeability, making it applicable to piece dyeing.

Check Digit Verification of cas no
The CAS Registry Mumber 12768-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,6 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12768-78:
(7*1)+(6*2)+(5*7)+(4*6)+(3*8)+(2*7)+(1*8)=124
124 % 10 = 4
So 12768-78-4 is a valid CAS Registry Number.
