Check Digit Verification of cas no

The CAS Registry Mumber 120280-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,8 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120280-33:
(8*1)+(7*2)+(6*0)+(5*2)+(4*8)+(3*0)+(2*3)+(1*3)=73
73 % 10 = 3
So 120280-33-3 is a valid CAS Registry Number.
