Check Digit Verification of cas no

The CAS Registry Mumber 40723-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40723-71:
(7*4)+(6*0)+(5*7)+(4*2)+(3*3)+(2*7)+(1*1)=95
95 % 10 = 5
So 40723-71-5 is a valid CAS Registry Number.
