Check Digit Verification of cas no

The CAS Registry Mumber 140476-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,7 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140476-16:
(8*1)+(7*4)+(6*0)+(5*4)+(4*7)+(3*6)+(2*1)+(1*6)=110
110 % 10 = 0
So 140476-16-0 is a valid CAS Registry Number.
