Check Digit Verification of cas no

The CAS Registry Mumber 1173893-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,8,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1173893-40:
(9*1)+(8*1)+(7*7)+(6*3)+(5*8)+(4*9)+(3*3)+(2*4)+(1*0)=177
177 % 10 = 7
So 1173893-40-7 is a valid CAS Registry Number.
