General Description
Direct Blue 279, also known as Acid Blue 92 or C.I. 74180, is a synthetic organic dye with the chemical formula C37H34N2Na2O9S3. It is commonly used in the textile industry for dyeing cotton and cellulose fibers, as well as in the production of paper, leather, and ink. Direct Blue 279 is a water-soluble dye, and it produces a bright blue color with good color fastness properties. However, it is a known skin and respiratory irritant, and it has potential eco-toxicity. Therefore, its use and disposal need to be managed carefully to minimize environmental impact and risks to human health.Check Digit Verification of cas no
The CAS Registry Mumber 72827-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,2 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 72827-89:
(7*7)+(6*2)+(5*8)+(4*2)+(3*7)+(2*8)+(1*9)=155
155 % 10 = 5
So 72827-89-5 is a valid CAS Registry Number.
