Check Digit Verification of cas no

The CAS Registry Mumber 3285-55-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,8 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3285-55:
(6*3)+(5*2)+(4*8)+(3*5)+(2*5)+(1*5)=90
90 % 10 = 0
So 3285-55-0 is a valid CAS Registry Number.
