23452-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23452-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,5 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 23452-53:
(7*2)+(6*3)+(5*4)+(4*5)+(3*2)+(2*5)+(1*3)=91
91 % 10 = 1
So 23452-53-1 is a valid CAS Registry Number.
