Check Digit Verification of cas no

The CAS Registry Mumber 1140970-19-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,9,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1140970-19:
(9*1)+(8*1)+(7*4)+(6*0)+(5*9)+(4*7)+(3*0)+(2*1)+(1*9)=129
129 % 10 = 9
So 1140970-19-9 is a valid CAS Registry Number.
