Check Digit Verification of cas no

The CAS Registry Mumber 138610-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,1 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138610-08:
(8*1)+(7*3)+(6*8)+(5*6)+(4*1)+(3*0)+(2*0)+(1*8)=119
119 % 10 = 9
So 138610-08-9 is a valid CAS Registry Number.
