Check Digit Verification of cas no

The CAS Registry Mumber 85808-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85808-53:
(7*8)+(6*5)+(5*8)+(4*0)+(3*8)+(2*5)+(1*3)=163
163 % 10 = 3
So 85808-53-3 is a valid CAS Registry Number.
