Check Digit Verification of cas no

The CAS Registry Mumber 857020-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,0,2 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 857020-28:
(8*8)+(7*5)+(6*7)+(5*0)+(4*2)+(3*0)+(2*2)+(1*8)=161
161 % 10 = 1
So 857020-28-1 is a valid CAS Registry Number.
