Check Digit Verification of cas no
The CAS Registry Mumber 74440-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74440-20:
(7*7)+(6*4)+(5*4)+(4*4)+(3*0)+(2*2)+(1*0)=113
113 % 10 = 3
So 74440-20-3 is a valid CAS Registry Number.
