Check Digit Verification of cas no

The CAS Registry Mumber 42513-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,1 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 42513-04:
(7*4)+(6*2)+(5*5)+(4*1)+(3*3)+(2*0)+(1*4)=82
82 % 10 = 2
So 42513-04-2 is a valid CAS Registry Number.
