Check Digit Verification of cas no

The CAS Registry Mumber 81933-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,3 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81933-89:
(7*8)+(6*1)+(5*9)+(4*3)+(3*3)+(2*8)+(1*9)=153
153 % 10 = 3
So 81933-89-3 is a valid CAS Registry Number.
