54221-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54221-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,2 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54221-11:
(7*5)+(6*4)+(5*2)+(4*2)+(3*1)+(2*1)+(1*1)=83
83 % 10 = 3
So 54221-11-3 is a valid CAS Registry Number.
