96504-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 96504-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,5,0 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 96504-03:
(7*9)+(6*6)+(5*5)+(4*0)+(3*4)+(2*0)+(1*3)=139
139 % 10 = 9
So 96504-03-9 is a valid CAS Registry Number.
