123864-74-4 Usage
General Description
Hydrogen chloride 1.25M in ethanol is a chemical lab reagent often used in various experimental and industrial processes. It is a high-concentration solution, composed mainly of hydrogen chloride, a diatomic molecule, dissolved in ethanol. Hydrogen chloride is a colorless gas, which forms white fumes of hydrochloric acid upon contact with the atmosphere. However, it readily dissolves in water and organic solvents such as ethanol. The resulting solution is highly corrosive and should be handled with caution. It finds applications in many areas including organic synthesis and pH adjustments in laboratories.
Check Digit Verification of cas no
The CAS Registry Mumber 123864-74-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,6 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123864-74:
(8*1)+(7*2)+(6*3)+(5*8)+(4*6)+(3*4)+(2*7)+(1*4)=134
134 % 10 = 4
So 123864-74-4 is a valid CAS Registry Number.
