117-88-4 Usage
General Description
The chemical 3-[[2-(acetylamino)-4-aminophenyl]azo]naphthalene-1,5-disulphonic acid, also known as Acid Orange 10, is an azo dye often used in the textile industry to dye cotton, wool, and silk. It is also used as a biological stain for microscopy. It is a bright orange-red powder that is soluble in water and ethanol. 3-[[2-(acetylamino)-4-aminophenyl]azo]naphthalene-1,5-disulphonic acid is known to be toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment. It also has the potential to be harmful if swallowed and can cause irritation to the skin and eyes. Due to its potential health and environmental hazards, it is important to handle and dispose of this chemical with care and in accordance with safety regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 117-88-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117-88:
(5*1)+(4*1)+(3*7)+(2*8)+(1*8)=54
54 % 10 = 4
So 117-88-4 is a valid CAS Registry Number.
