Check Digit Verification of cas no

The CAS Registry Mumber 1234320-00-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,3,2 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1234320-00:
(9*1)+(8*2)+(7*3)+(6*4)+(5*3)+(4*2)+(3*0)+(2*0)+(1*0)=93
93 % 10 = 3
So 1234320-00-3 is a valid CAS Registry Number.
