Check Digit Verification of cas no

The CAS Registry Mumber 160251-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,5 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160251-99:
(8*1)+(7*6)+(6*0)+(5*2)+(4*5)+(3*1)+(2*9)+(1*9)=110
110 % 10 = 0
So 160251-99-0 is a valid CAS Registry Number.
