Check Digit Verification of cas no

The CAS Registry Mumber 135559-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,5 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135559-16:
(8*1)+(7*3)+(6*5)+(5*5)+(4*5)+(3*9)+(2*1)+(1*6)=139
139 % 10 = 9
So 135559-16-9 is a valid CAS Registry Number.
