Check Digit Verification of cas no

The CAS Registry Mumber 16903-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,0 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16903-61:
(7*1)+(6*6)+(5*9)+(4*0)+(3*3)+(2*6)+(1*1)=110
110 % 10 = 0
So 16903-61-0 is a valid CAS Registry Number.
