Check Digit Verification of cas no

The CAS Registry Mumber 1119249-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,9,2,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1119249-75:
(9*1)+(8*1)+(7*1)+(6*9)+(5*2)+(4*4)+(3*9)+(2*7)+(1*5)=150
150 % 10 = 0
So 1119249-75-0 is a valid CAS Registry Number.
