Check Digit Verification of cas no

The CAS Registry Mumber 28606-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,0 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28606-01:
(7*2)+(6*8)+(5*6)+(4*0)+(3*6)+(2*0)+(1*1)=111
111 % 10 = 1
So 28606-01-1 is a valid CAS Registry Number.
