Check Digit Verification of cas no

The CAS Registry Mumber 1109-17-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1109-17:
(6*1)+(5*1)+(4*0)+(3*9)+(2*1)+(1*7)=47
47 % 10 = 7
So 1109-17-7 is a valid CAS Registry Number.
