Check Digit Verification of cas no

The CAS Registry Mumber 73311-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73311-20:
(7*7)+(6*3)+(5*3)+(4*1)+(3*1)+(2*2)+(1*0)=93
93 % 10 = 3
So 73311-20-3 is a valid CAS Registry Number.
