Check Digit Verification of cas no

The CAS Registry Mumber 144558-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,5 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144558-63:
(8*1)+(7*4)+(6*4)+(5*5)+(4*5)+(3*8)+(2*6)+(1*3)=144
144 % 10 = 4
So 144558-63-4 is a valid CAS Registry Number.
