Check Digit Verification of cas no

The CAS Registry Mumber 7331-84-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7331-84:
(6*7)+(5*3)+(4*3)+(3*1)+(2*8)+(1*4)=92
92 % 10 = 2
So 7331-84-2 is a valid CAS Registry Number.
