104503-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104503-07-3 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 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104503-07:
(8*1)+(7*0)+(6*4)+(5*5)+(4*0)+(3*3)+(2*0)+(1*7)=73
73 % 10 = 3
So 104503-07-3 is a valid CAS Registry Number.
