104502-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104502-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,0 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104502-09:
(8*1)+(7*0)+(6*4)+(5*5)+(4*0)+(3*2)+(2*0)+(1*9)=72
72 % 10 = 2
So 104502-09-2 is a valid CAS Registry Number.
