59453-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59453-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,5 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59453-63:
(7*5)+(6*9)+(5*4)+(4*5)+(3*3)+(2*6)+(1*3)=153
153 % 10 = 3
So 59453-63-3 is a valid CAS Registry Number.
