Check Digit Verification of cas no

The CAS Registry Mumber 648-84-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 648-84:
(5*6)+(4*4)+(3*8)+(2*8)+(1*4)=90
90 % 10 = 0
So 648-84-0 is a valid CAS Registry Number.
