Check Digit Verification of cas no

The CAS Registry Mumber 122040-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,4 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122040-09:
(8*1)+(7*2)+(6*2)+(5*0)+(4*4)+(3*0)+(2*0)+(1*9)=59
59 % 10 = 9
So 122040-09-9 is a valid CAS Registry Number.
