1146-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1146-73-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1146-73:
(6*1)+(5*1)+(4*4)+(3*6)+(2*7)+(1*3)=62
62 % 10 = 2
So 1146-73-2 is a valid CAS Registry Number.
