Check Digit Verification of cas no

The CAS Registry Mumber 139930-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139930-67:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*0)+(2*6)+(1*7)=159
159 % 10 = 9
So 139930-67-9 is a valid CAS Registry Number.
