Check Digit Verification of cas no

The CAS Registry Mumber 3491-13-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3491-13:
(6*3)+(5*4)+(4*9)+(3*1)+(2*1)+(1*3)=82
82 % 10 = 2
So 3491-13-2 is a valid CAS Registry Number.
