59118-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59118-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,1 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 59118-28:
(7*5)+(6*9)+(5*1)+(4*1)+(3*8)+(2*2)+(1*8)=134
134 % 10 = 4
So 59118-28-4 is a valid CAS Registry Number.
