General Description
The chemical 4-amino-5-(tosyloxy)naphthalene-2,7-disulfonic acid, also known as Acid Orange 35, is a fluorescent dye commonly used in biological research and in the production of colored plastics. Its chemical structure consists of a naphthalene core with amino and tosyloxy functional groups attached, as well as sulfonic acid groups at positions 2 and 7 on the naphthalene ring. 4-amino-5-(tosyloxy)naphthalene-2,7-disulfonic acid is water soluble and exhibits strong fluorescence when excited by ultraviolet light. It is often used as a fluorescent tracer in cell biology studies and as a colorant in various industrial processes. However, it is important to handle this chemical with care, as it is toxic if ingested or inhaled and can cause irritation to the skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 6837-93-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,3 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6837-93:
(6*6)+(5*8)+(4*3)+(3*7)+(2*9)+(1*3)=130
130 % 10 = 0
So 6837-93-0 is a valid CAS Registry Number.
