Check Digit Verification of cas no

The CAS Registry Mumber 139903-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,0 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139903-89:
(8*1)+(7*3)+(6*9)+(5*9)+(4*0)+(3*3)+(2*8)+(1*9)=162
162 % 10 = 2
So 139903-89-2 is a valid CAS Registry Number.
