129-96-4 Usage
General Description
Chromotropic acid disodium salt is a chemical compound commonly used as an indicator in the determination of metals, particularly in complexometric titrations. It is a water-soluble, yellow or orange powder that changes color based on the presence of certain metal ions. CHROMOTROPIC ACID DISODIUM SALT is known for its high selectivity and sensitivity to different metal ions, making it valuable for analytical chemistry applications. Additionally, it is also used in the synthesis of various organic compounds and in the preparation of reagents for analysis and research purposes. However, it is important to handle this chemical with care and to follow proper safety precautions due to its potential irritant and harmful effects.
Check Digit Verification of cas no
The CAS Registry Mumber 129-96-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129-96:
(5*1)+(4*2)+(3*9)+(2*9)+(1*6)=64
64 % 10 = 4
So 129-96-4 is a valid CAS Registry Number.
