Check Digit Verification of cas no

The CAS Registry Mumber 1094598-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,4,5,9 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1094598-75:
(9*1)+(8*0)+(7*9)+(6*4)+(5*5)+(4*9)+(3*8)+(2*7)+(1*5)=200
200 % 10 = 0
So 1094598-75-0 is a valid CAS Registry Number.
