1466-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1466-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,6 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1466-21:
(6*1)+(5*4)+(4*6)+(3*6)+(2*2)+(1*1)=73
73 % 10 = 3
So 1466-21-3 is a valid CAS Registry Number.
