Check Digit Verification of cas no

The CAS Registry Mumber 139330-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,3 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139330-25:
(8*1)+(7*3)+(6*9)+(5*3)+(4*3)+(3*0)+(2*2)+(1*5)=119
119 % 10 = 9
So 139330-25-9 is a valid CAS Registry Number.
