Check Digit Verification of cas no

The CAS Registry Mumber 98620-93-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,2 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98620-93:
(7*9)+(6*8)+(5*6)+(4*2)+(3*0)+(2*9)+(1*3)=170
170 % 10 = 0
So 98620-93-0 is a valid CAS Registry Number.
