Check Digit Verification of cas no

The CAS Registry Mumber 138983-31-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138983-31:
(8*1)+(7*3)+(6*8)+(5*9)+(4*8)+(3*3)+(2*3)+(1*1)=170
170 % 10 = 0
So 138983-31-0 is a valid CAS Registry Number.
