Check Digit Verification of cas no

The CAS Registry Mumber 113451-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,5 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113451-30:
(8*1)+(7*1)+(6*3)+(5*4)+(4*5)+(3*1)+(2*3)+(1*0)=82
82 % 10 = 2
So 113451-30-2 is a valid CAS Registry Number.
