Check Digit Verification of cas no

The CAS Registry Mumber 842-68-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 842-68:
(5*8)+(4*4)+(3*2)+(2*6)+(1*8)=82
82 % 10 = 2
So 842-68-2 is a valid CAS Registry Number.
