Check Digit Verification of cas no
The CAS Registry Mumber 5413-69-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5413-69:
(6*5)+(5*4)+(4*1)+(3*3)+(2*6)+(1*9)=84
84 % 10 = 4
So 5413-69-4 is a valid CAS Registry Number.
