Check Digit Verification of cas no

The CAS Registry Mumber 1123103-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,1,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1123103-72:
(9*1)+(8*1)+(7*2)+(6*3)+(5*1)+(4*0)+(3*3)+(2*7)+(1*2)=79
79 % 10 = 9
So 1123103-72-9 is a valid CAS Registry Number.
