Check Digit Verification of cas no

The CAS Registry Mumber 1185249-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,2,4 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1185249-40:
(9*1)+(8*1)+(7*8)+(6*5)+(5*2)+(4*4)+(3*9)+(2*4)+(1*0)=164
164 % 10 = 4
So 1185249-40-4 is a valid CAS Registry Number.
