503533-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 503533-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,5,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 503533-74:
(8*5)+(7*0)+(6*3)+(5*5)+(4*3)+(3*3)+(2*7)+(1*4)=122
122 % 10 = 2
So 503533-74-2 is a valid CAS Registry Number.
