5471-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5471-16-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,7 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5471-16:
(6*5)+(5*4)+(4*7)+(3*1)+(2*1)+(1*6)=89
89 % 10 = 9
So 5471-16-9 is a valid CAS Registry Number.
