Check Digit Verification of cas no

The CAS Registry Mumber 2689-17-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2689-17:
(6*2)+(5*6)+(4*8)+(3*9)+(2*1)+(1*7)=110
110 % 10 = 0
So 2689-17-0 is a valid CAS Registry Number.
