Check Digit Verification of cas no

The CAS Registry Mumber 5243-84-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,4 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5243-84:
(6*5)+(5*2)+(4*4)+(3*3)+(2*8)+(1*4)=85
85 % 10 = 5
So 5243-84-5 is a valid CAS Registry Number.
