Check Digit Verification of cas no

The CAS Registry Mumber 33238-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33238-16:
(7*3)+(6*3)+(5*2)+(4*3)+(3*8)+(2*1)+(1*6)=93
93 % 10 = 3
So 33238-16-3 is a valid CAS Registry Number.
