Check Digit Verification of cas no

The CAS Registry Mumber 4842-03-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4842-03:
(6*4)+(5*8)+(4*4)+(3*2)+(2*0)+(1*3)=89
89 % 10 = 9
So 4842-03-9 is a valid CAS Registry Number.
