Check Digit Verification of cas no

The CAS Registry Mumber 1161924-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,9,2 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1161924-75:
(9*1)+(8*1)+(7*6)+(6*1)+(5*9)+(4*2)+(3*4)+(2*7)+(1*5)=149
149 % 10 = 9
So 1161924-75-9 is a valid CAS Registry Number.
