Check Digit Verification of cas no

The CAS Registry Mumber 4545-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4545-20:
(6*4)+(5*5)+(4*4)+(3*5)+(2*2)+(1*0)=84
84 % 10 = 4
So 4545-20-4 is a valid CAS Registry Number.
