54118-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54118-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,1 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54118-71:
(7*5)+(6*4)+(5*1)+(4*1)+(3*8)+(2*7)+(1*1)=107
107 % 10 = 7
So 54118-71-7 is a valid CAS Registry Number.
