Check Digit Verification of cas no

The CAS Registry Mumber 56548-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,4 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56548-44:
(7*5)+(6*6)+(5*5)+(4*4)+(3*8)+(2*4)+(1*4)=148
148 % 10 = 8
So 56548-44-8 is a valid CAS Registry Number.
