6345-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6345-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,4 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 6345-73:
(6*6)+(5*3)+(4*4)+(3*5)+(2*7)+(1*3)=99
99 % 10 = 9
So 6345-73-9 is a valid CAS Registry Number.
