Check Digit Verification of cas no

The CAS Registry Mumber 1131004-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,0,0 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1131004-91:
(9*1)+(8*1)+(7*3)+(6*1)+(5*0)+(4*0)+(3*4)+(2*9)+(1*1)=75
75 % 10 = 5
So 1131004-91-5 is a valid CAS Registry Number.
