Check Digit Verification of cas no

The CAS Registry Mumber 84021-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,2 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84021-52:
(7*8)+(6*4)+(5*0)+(4*2)+(3*1)+(2*5)+(1*2)=103
103 % 10 = 3
So 84021-52-3 is a valid CAS Registry Number.
