Check Digit Verification of cas no

The CAS Registry Mumber 1129540-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,5,4 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1129540-29:
(9*1)+(8*1)+(7*2)+(6*9)+(5*5)+(4*4)+(3*0)+(2*2)+(1*9)=139
139 % 10 = 9
So 1129540-29-9 is a valid CAS Registry Number.
