Phenol-1,2-naphthalein, also known as phenolphthalein, is a colorless, crystalline organic compound widely used as a pH indicator. It is derived from phenol and phthalic anhydride, with the chemical formula C20H14O4. Phenolphthalein is colorless in acidic solutions and turns pink to deep magenta in basic solutions, making it a useful tool for determining the pH of a solution. It is non-toxic and has a wide pH range of 8.2 to 10.0, where it exhibits a color change. This chemical is commonly used in laboratories, educational settings, and various industrial applications to monitor the acidity or alkalinity of solutions.

5768-91-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5768-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5768-91:
(6*5)+(5*7)+(4*6)+(3*8)+(2*9)+(1*1)=132
132 % 10 = 2
So 5768-91-2 is a valid CAS Registry Number.
