Check Digit Verification of cas no

The CAS Registry Mumber 5247-74-5 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 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5247-74:
(6*5)+(5*2)+(4*4)+(3*7)+(2*7)+(1*4)=95
95 % 10 = 5
So 5247-74-5 is a valid CAS Registry Number.
