General Description
NITROSULFONAZO III is a water-soluble, azo dye that is commonly used as a pH indicator in laboratory testing. It is a member of the sulfonazobenzene class of dyes and is known for its bright red color in acidic environments and bright yellow color in alkaline environments. NITROSULFONAZO III has a molecular structure that contains both nitro and sulfonic acid groups, making it suitable for reactions involving both acidic and basic conditions. It is also used in various biochemical and microbiological applications due to its ability to accurately and reliably measure pH levels in a wide range of substances. Additionally, it is sometimes used as a dye in the textile industry. However, it is important to handle NITROSULFONAZO III with care, as it is classified as a hazardous chemical compound.
Check Digit Verification of cas no
The CAS Registry Mumber 1964-89-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1964-89:
(6*1)+(5*9)+(4*6)+(3*4)+(2*8)+(1*9)=112
112 % 10 = 2
So 1964-89-2 is a valid CAS Registry Number.
