54903-58-1 Usage
Preparation
Preparation from 3-methyl-6-propionylbenzoxazolinone by alkaline hydrolysis with boiling 10% aqueous sodium hydroxide solution for 4 h (90–100%).
Check Digit Verification of cas no
The CAS Registry Mumber 54903-58-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,0 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54903-58:
(7*5)+(6*4)+(5*9)+(4*0)+(3*3)+(2*5)+(1*8)=131
131 % 10 = 1
So 54903-58-1 is a valid CAS Registry Number.
