54199-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54199-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54199-20:
(7*5)+(6*4)+(5*1)+(4*9)+(3*9)+(2*2)+(1*0)=131
131 % 10 = 1
So 54199-20-1 is a valid CAS Registry Number.
