84304-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84304-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,0 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84304-73:
(7*8)+(6*4)+(5*3)+(4*0)+(3*4)+(2*7)+(1*3)=124
124 % 10 = 4
So 84304-73-4 is a valid CAS Registry Number.
