Check Digit Verification of cas no

The CAS Registry Mumber 70031-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70031-89:
(7*7)+(6*0)+(5*0)+(4*3)+(3*1)+(2*8)+(1*9)=89
89 % 10 = 9
So 70031-89-9 is a valid CAS Registry Number.
