Check Digit Verification of cas no

The CAS Registry Mumber 20405-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,0 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20405-64:
(7*2)+(6*0)+(5*4)+(4*0)+(3*5)+(2*6)+(1*4)=65
65 % 10 = 5
So 20405-64-5 is a valid CAS Registry Number.
