Check Digit Verification of cas no

The CAS Registry Mumber 105039-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 105039-98:
(8*1)+(7*0)+(6*5)+(5*0)+(4*3)+(3*9)+(2*9)+(1*8)=103
103 % 10 = 3
So 105039-98-3 is a valid CAS Registry Number.
