Check Digit Verification of cas no
The CAS Registry Mumber 80407-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,0 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80407-56:
(7*8)+(6*0)+(5*4)+(4*0)+(3*7)+(2*5)+(1*6)=113
113 % 10 = 3
So 80407-56-3 is a valid CAS Registry Number.
