Check Digit Verification of cas no

The CAS Registry Mumber 1280220-11-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1280220-11:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*2)+(3*0)+(2*1)+(1*1)=102
102 % 10 = 2
So 1280220-11-2 is a valid CAS Registry Number.
