Check Digit Verification of cas no

The CAS Registry Mumber 139640-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139640-55:
(8*1)+(7*3)+(6*9)+(5*6)+(4*4)+(3*0)+(2*5)+(1*5)=144
144 % 10 = 4
So 139640-55-4 is a valid CAS Registry Number.
