Check Digit Verification of cas no

The CAS Registry Mumber 16253-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,5 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16253-00:
(7*1)+(6*6)+(5*2)+(4*5)+(3*3)+(2*0)+(1*0)=82
82 % 10 = 2
So 16253-00-2 is a valid CAS Registry Number.
