Check Digit Verification of cas no

The CAS Registry Mumber 136880-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,8 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136880-28:
(8*1)+(7*3)+(6*6)+(5*8)+(4*8)+(3*0)+(2*2)+(1*8)=149
149 % 10 = 9
So 136880-28-9 is a valid CAS Registry Number.
