473-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 473-50-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 473-50:
(5*4)+(4*7)+(3*3)+(2*5)+(1*0)=67
67 % 10 = 7
So 473-50-7 is a valid CAS Registry Number.
