Check Digit Verification of cas no

The CAS Registry Mumber 1318239-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,2,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1318239-40:
(9*1)+(8*3)+(7*1)+(6*8)+(5*2)+(4*3)+(3*9)+(2*4)+(1*0)=145
145 % 10 = 5
So 1318239-40-5 is a valid CAS Registry Number.
