Check Digit Verification of cas no
The CAS Registry Mumber 58168-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,1,6 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58168-20:
(7*5)+(6*8)+(5*1)+(4*6)+(3*8)+(2*2)+(1*0)=140
140 % 10 = 0
So 58168-20-0 is a valid CAS Registry Number.
