Check Digit Verification of cas no
The CAS Registry Mumber 18181-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,8 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18181-08:
(7*1)+(6*8)+(5*1)+(4*8)+(3*1)+(2*0)+(1*8)=103
103 % 10 = 3
So 18181-08-3 is a valid CAS Registry Number.
