21161-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21161-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21161-28:
(7*2)+(6*1)+(5*1)+(4*6)+(3*1)+(2*2)+(1*8)=64
64 % 10 = 4
So 21161-28-4 is a valid CAS Registry Number.
