Check Digit Verification of cas no

The CAS Registry Mumber 40110-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,1 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40110-68:
(7*4)+(6*0)+(5*1)+(4*1)+(3*0)+(2*6)+(1*8)=57
57 % 10 = 7
So 40110-68-7 is a valid CAS Registry Number.
