Check Digit Verification of cas no

The CAS Registry Mumber 1109-54-2 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, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1109-54:
(6*1)+(5*1)+(4*0)+(3*9)+(2*5)+(1*4)=52
52 % 10 = 2
So 1109-54-2 is a valid CAS Registry Number.
