Check Digit Verification of cas no

The CAS Registry Mumber 1258326-14-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,3,2 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1258326-14:
(9*1)+(8*2)+(7*5)+(6*8)+(5*3)+(4*2)+(3*6)+(2*1)+(1*4)=155
155 % 10 = 5
So 1258326-14-5 is a valid CAS Registry Number.
