Check Digit Verification of cas no

The CAS Registry Mumber 1185985-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,9,8 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1185985-41:
(9*1)+(8*1)+(7*8)+(6*5)+(5*9)+(4*8)+(3*5)+(2*4)+(1*1)=204
204 % 10 = 4
So 1185985-41-4 is a valid CAS Registry Number.
