Check Digit Verification of cas no

The CAS Registry Mumber 100250-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,5 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 100250-48:
(8*1)+(7*0)+(6*0)+(5*2)+(4*5)+(3*0)+(2*4)+(1*8)=54
54 % 10 = 4
So 100250-48-4 is a valid CAS Registry Number.
