Check Digit Verification of cas no

The CAS Registry Mumber 1220125-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,1,2 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1220125-52:
(9*1)+(8*2)+(7*2)+(6*0)+(5*1)+(4*2)+(3*5)+(2*5)+(1*2)=79
79 % 10 = 9
So 1220125-52-9 is a valid CAS Registry Number.
