Check Digit Verification of cas no

The CAS Registry Mumber 393-78-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 393-78:
(5*3)+(4*9)+(3*3)+(2*7)+(1*8)=82
82 % 10 = 2
So 393-78-2 is a valid CAS Registry Number.
