99504-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99504-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99504-76:
(7*9)+(6*9)+(5*5)+(4*0)+(3*4)+(2*7)+(1*6)=174
174 % 10 = 4
So 99504-76-4 is a valid CAS Registry Number.
