Check Digit Verification of cas no

The CAS Registry Mumber 5185-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5185-99:
(6*5)+(5*1)+(4*8)+(3*5)+(2*9)+(1*9)=109
109 % 10 = 9
So 5185-99-9 is a valid CAS Registry Number.
