Check Digit Verification of cas no

The CAS Registry Mumber 139210-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139210-19:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*0)+(2*1)+(1*9)=108
108 % 10 = 8
So 139210-19-8 is a valid CAS Registry Number.
