144632-53-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144632-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,3 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144632-53:
(8*1)+(7*4)+(6*4)+(5*6)+(4*3)+(3*2)+(2*5)+(1*3)=121
121 % 10 = 1
So 144632-53-1 is a valid CAS Registry Number.
