Check Digit Verification of cas no

The CAS Registry Mumber 14511-67-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14511-67:
(7*1)+(6*4)+(5*5)+(4*1)+(3*1)+(2*6)+(1*7)=82
82 % 10 = 2
So 14511-67-2 is a valid CAS Registry Number.
