Check Digit Verification of cas no

The CAS Registry Mumber 427-47-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 427-47:
(5*4)+(4*2)+(3*7)+(2*4)+(1*7)=64
64 % 10 = 4
So 427-47-4 is a valid CAS Registry Number.
