12239-31-5 Usage
General Description
Direct Green 27, also known as Green M, is a compound used as a chemical dye. This green pigment is part of the azo class of dyes, which are notable for their vibrant coloring properties. It mainly serves in the textile and paper industries due to its ability to directly dye cellulose fibers. Its manufacture involves the coupling reaction between diazotized Chloramine-T, and N-methyl-1,4-benzenediamine. It is highly soluble in water and presents potential environmental hazard due to its low biodegradability.Check Digit Verification of cas no
The CAS Registry Mumber 12239-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.Calculate Digit Verification of CAS Registry Number 12239-31:
(7*1)+(6*2)+(5*2)+(4*3)+(3*9)+(2*3)+(1*1)=75
75 % 10 = 5
So 12239-31-5 is a valid CAS Registry Number.
