Check Digit Verification of cas no

The CAS Registry Mumber 1103520-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,3,5,2 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1103520-01:
(9*1)+(8*1)+(7*0)+(6*3)+(5*5)+(4*2)+(3*0)+(2*0)+(1*1)=69
69 % 10 = 9
So 1103520-01-9 is a valid CAS Registry Number.
