Check Digit Verification of cas no

The CAS Registry Mumber 163890-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,9 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163890-71:
(8*1)+(7*6)+(6*3)+(5*8)+(4*9)+(3*0)+(2*7)+(1*1)=159
159 % 10 = 9
So 163890-71-9 is a valid CAS Registry Number.
