Check Digit Verification of cas no
The CAS Registry Mumber 12081-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,8 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12081-16:
(7*1)+(6*2)+(5*0)+(4*8)+(3*1)+(2*1)+(1*6)=62
62 % 10 = 2
So 12081-16-2 is a valid CAS Registry Number.
