Check Digit Verification of cas no

The CAS Registry Mumber 904660-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,6 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 904660-46:
(8*9)+(7*0)+(6*4)+(5*6)+(4*6)+(3*0)+(2*4)+(1*6)=164
164 % 10 = 4
So 904660-46-4 is a valid CAS Registry Number.
