Check Digit Verification of cas no

The CAS Registry Mumber 116221-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,2,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116221-99:
(8*1)+(7*1)+(6*6)+(5*2)+(4*2)+(3*1)+(2*9)+(1*9)=99
99 % 10 = 9
So 116221-99-9 is a valid CAS Registry Number.
