Check Digit Verification of cas no

The CAS Registry Mumber 1309581-24-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,5,8 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1309581-24:
(9*1)+(8*3)+(7*0)+(6*9)+(5*5)+(4*8)+(3*1)+(2*2)+(1*4)=155
155 % 10 = 5
So 1309581-24-5 is a valid CAS Registry Number.
