Check Digit Verification of cas no

The CAS Registry Mumber 81820-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,2 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81820-01:
(7*8)+(6*1)+(5*8)+(4*2)+(3*0)+(2*0)+(1*1)=111
111 % 10 = 1
So 81820-01-1 is a valid CAS Registry Number.
