Check Digit Verification of cas no

The CAS Registry Mumber 1240182-11-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,8 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240182-11:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*8)+(3*2)+(2*1)+(1*1)=99
99 % 10 = 9
So 1240182-11-9 is a valid CAS Registry Number.
