Check Digit Verification of cas no

The CAS Registry Mumber 139426-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,2 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139426-64:
(8*1)+(7*3)+(6*9)+(5*4)+(4*2)+(3*6)+(2*6)+(1*4)=145
145 % 10 = 5
So 139426-64-5 is a valid CAS Registry Number.
