Check Digit Verification of cas no

The CAS Registry Mumber 159489-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,4,8 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159489-36:
(8*1)+(7*5)+(6*9)+(5*4)+(4*8)+(3*9)+(2*3)+(1*6)=188
188 % 10 = 8
So 159489-36-8 is a valid CAS Registry Number.
