Check Digit Verification of cas no
The CAS Registry Mumber 68186-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68186-91:
(7*6)+(6*8)+(5*1)+(4*8)+(3*6)+(2*9)+(1*1)=164
164 % 10 = 4
So 68186-91-4 is a valid CAS Registry Number.
