Check Digit Verification of cas no

The CAS Registry Mumber 201280-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,8 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 201280-41:
(8*2)+(7*0)+(6*1)+(5*2)+(4*8)+(3*0)+(2*4)+(1*1)=73
73 % 10 = 3
So 201280-41-3 is a valid CAS Registry Number.
