Check Digit Verification of cas no

The CAS Registry Mumber 80473-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,7 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80473-38:
(7*8)+(6*0)+(5*4)+(4*7)+(3*3)+(2*3)+(1*8)=127
127 % 10 = 7
So 80473-38-7 is a valid CAS Registry Number.
