Check Digit Verification of cas no

The CAS Registry Mumber 1688-90-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1688-90:
(6*1)+(5*6)+(4*8)+(3*8)+(2*9)+(1*0)=110
110 % 10 = 0
So 1688-90-0 is a valid CAS Registry Number.
