Check Digit Verification of cas no

The CAS Registry Mumber 203722-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,2 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 203722-34:
(8*2)+(7*0)+(6*3)+(5*7)+(4*2)+(3*2)+(2*3)+(1*4)=93
93 % 10 = 3
So 203722-34-3 is a valid CAS Registry Number.
