Check Digit Verification of cas no

The CAS Registry Mumber 130336-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,3,3 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130336-16:
(8*1)+(7*3)+(6*0)+(5*3)+(4*3)+(3*6)+(2*1)+(1*6)=82
82 % 10 = 2
So 130336-16-2 is a valid CAS Registry Number.
