161190-54-1 Usage
General Description
1-Propanol, 3-[[1-(2-methylphenyl)-1H-imidazol-2-yl]thio]-, also known as thymol blue, is a chemical compound commonly used as a pH indicator in laboratory settings. It appears as a yellow or red crystalline powder and is soluble in water, alcohol, and acetone. Thymol blue is often used in experiments to determine the pH of a solution by changing color in response to the acidic or alkaline environment. It is also utilized in the medical field as a diagnostic tool for conditions such as gastrointestinal reflux and helicobacter pylori infection. However, thymol blue should be handled with caution as it may be harmful if ingested or if it comes into contact with skin or eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 161190-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,9 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161190-54:
(8*1)+(7*6)+(6*1)+(5*1)+(4*9)+(3*0)+(2*5)+(1*4)=111
111 % 10 = 1
So 161190-54-1 is a valid CAS Registry Number.
