Check Digit Verification of cas no

The CAS Registry Mumber 12039-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12039-85:
(7*1)+(6*2)+(5*0)+(4*3)+(3*9)+(2*8)+(1*5)=79
79 % 10 = 9
So 12039-85-9 is a valid CAS Registry Number.
