Check Digit Verification of cas no

The CAS Registry Mumber 121125-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,2 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121125-67:
(8*1)+(7*2)+(6*1)+(5*1)+(4*2)+(3*5)+(2*6)+(1*7)=75
75 % 10 = 5
So 121125-67-5 is a valid CAS Registry Number.
