Check Digit Verification of cas no

The CAS Registry Mumber 84490-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,9 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84490-58:
(7*8)+(6*4)+(5*4)+(4*9)+(3*0)+(2*5)+(1*8)=154
154 % 10 = 4
So 84490-58-4 is a valid CAS Registry Number.
