Check Digit Verification of cas no

The CAS Registry Mumber 684-66-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 684-66:
(5*6)+(4*8)+(3*4)+(2*6)+(1*6)=92
92 % 10 = 2
So 684-66-2 is a valid CAS Registry Number.
