54191-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54191-99-0 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 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54191-99:
(7*5)+(6*4)+(5*1)+(4*9)+(3*1)+(2*9)+(1*9)=130
130 % 10 = 0
So 54191-99-0 is a valid CAS Registry Number.
