Check Digit Verification of cas no

The CAS Registry Mumber 400-71-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 400-71:
(5*4)+(4*0)+(3*0)+(2*7)+(1*1)=35
35 % 10 = 5
So 400-71-5 is a valid CAS Registry Number.
