Check Digit Verification of cas no

The CAS Registry Mumber 1123535-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,5,3 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1123535-40:
(9*1)+(8*1)+(7*2)+(6*3)+(5*5)+(4*3)+(3*5)+(2*4)+(1*0)=109
109 % 10 = 9
So 1123535-40-9 is a valid CAS Registry Number.
