Check Digit Verification of cas no

The CAS Registry Mumber 120511-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,1 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120511-91:
(8*1)+(7*2)+(6*0)+(5*5)+(4*1)+(3*1)+(2*9)+(1*1)=73
73 % 10 = 3
So 120511-91-3 is a valid CAS Registry Number.
