Check Digit Verification of cas no

The CAS Registry Mumber 1123075-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,0,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1123075-19:
(9*1)+(8*1)+(7*2)+(6*3)+(5*0)+(4*7)+(3*5)+(2*1)+(1*9)=103
103 % 10 = 3
So 1123075-19-3 is a valid CAS Registry Number.
