General Description
Sodium 5-amino-4-methoxy-2-nitrobenzenesulphonate, also known as methyl orange, is a synthetic organic compound commonly used as a pH indicator in laboratory applications. It is a water-soluble salt that appears as a reddish-orange powder and is commonly used in titration experiments to determine the endpoint of acid-base reactions. Methyl orange changes color from red to yellow at a pH of around 3.1 to 4.4, making it useful for distinguishing between acidic and alkaline solutions. Additionally, it is used in the textile industry as a dye and in the production of paper and leather. However, it is important to handle this chemical with care, as it can be toxic if ingested or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 59312-73-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,3,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59312-73:
(7*5)+(6*9)+(5*3)+(4*1)+(3*2)+(2*7)+(1*3)=131
131 % 10 = 1
So 59312-73-1 is a valid CAS Registry Number.
