Check Digit Verification of cas no

The CAS Registry Mumber 633282-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,3,2,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 633282-90:
(8*6)+(7*3)+(6*3)+(5*2)+(4*8)+(3*2)+(2*9)+(1*0)=153
153 % 10 = 3
So 633282-90-3 is a valid CAS Registry Number.
