Check Digit Verification of cas no

The CAS Registry Mumber 139449-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139449-41:
(8*1)+(7*3)+(6*9)+(5*4)+(4*4)+(3*9)+(2*4)+(1*1)=155
155 % 10 = 5
So 139449-41-5 is a valid CAS Registry Number.
