Chemical Properties
Violet crystals. Insoluble in water, soluble in glacial acetic acid and hot benzene.Uses
As indicator in saturated alcoholic solution. pH: pink 0.0 to yellow 1.6; yellow 6.0 to green 7.6.Definition
ChEBI: An organic heterotetracyclic compound that is naphtho[2,3-f]quinoline-7,12-dione carrying two additional hydroxy groups at positions 5 and 6. Used as an acid-base indicator. Between pH 0.0 and pH 1.6 it changes from pink to yellow, and between pH 6.0 and pH 7.6 it changes from yellow to green.Check Digit Verification of cas no
The CAS Registry Mumber 568-02-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 568-02:
(5*5)+(4*6)+(3*8)+(2*0)+(1*2)=75
75 % 10 = 5
So 568-02-5 is a valid CAS Registry Number.
