Check Digit Verification of cas no

The CAS Registry Mumber 438-95-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 438-95:
(5*4)+(4*3)+(3*8)+(2*9)+(1*5)=79
79 % 10 = 9
So 438-95-9 is a valid CAS Registry Number.
