Check Digit Verification of cas no

The CAS Registry Mumber 821-85-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 821-85:
(5*8)+(4*2)+(3*1)+(2*8)+(1*5)=72
72 % 10 = 2
So 821-85-2 is a valid CAS Registry Number.
