Check Digit Verification of cas no

The CAS Registry Mumber 103991-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,9 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103991-28:
(8*1)+(7*0)+(6*3)+(5*9)+(4*9)+(3*1)+(2*2)+(1*8)=122
122 % 10 = 2
So 103991-28-2 is a valid CAS Registry Number.
