Check Digit Verification of cas no

The CAS Registry Mumber 1335103-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,1,0 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1335103-52:
(9*1)+(8*3)+(7*3)+(6*5)+(5*1)+(4*0)+(3*3)+(2*5)+(1*2)=110
110 % 10 = 0
So 1335103-52-0 is a valid CAS Registry Number.
