Check Digit Verification of cas no

The CAS Registry Mumber 478-07-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 478-07:
(5*4)+(4*7)+(3*8)+(2*0)+(1*7)=79
79 % 10 = 9
So 478-07-9 is a valid CAS Registry Number.
