Check Digit Verification of cas no

The CAS Registry Mumber 1040187-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,1,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1040187-70:
(9*1)+(8*0)+(7*4)+(6*0)+(5*1)+(4*8)+(3*7)+(2*7)+(1*0)=109
109 % 10 = 9
So 1040187-70-9 is a valid CAS Registry Number.
