Check Digit Verification of cas no

The CAS Registry Mumber 20845-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20845-16:
(7*2)+(6*0)+(5*8)+(4*4)+(3*5)+(2*1)+(1*6)=93
93 % 10 = 3
So 20845-16-3 is a valid CAS Registry Number.
