Check Digit Verification of cas no

The CAS Registry Mumber 904633-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,3 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 904633-64:
(8*9)+(7*0)+(6*4)+(5*6)+(4*3)+(3*3)+(2*6)+(1*4)=163
163 % 10 = 3
So 904633-64-3 is a valid CAS Registry Number.
