Check Digit Verification of cas no

The CAS Registry Mumber 1190308-75-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,3,0 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1190308-75:
(9*1)+(8*1)+(7*9)+(6*0)+(5*3)+(4*0)+(3*8)+(2*7)+(1*5)=138
138 % 10 = 8
So 1190308-75-8 is a valid CAS Registry Number.
