Check Digit Verification of cas no

The CAS Registry Mumber 146448-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,4 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146448-52:
(8*1)+(7*4)+(6*6)+(5*4)+(4*4)+(3*8)+(2*5)+(1*2)=144
144 % 10 = 4
So 146448-52-4 is a valid CAS Registry Number.
