154458-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154458-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,4,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154458-53:
(8*1)+(7*5)+(6*4)+(5*4)+(4*5)+(3*8)+(2*5)+(1*3)=144
144 % 10 = 4
So 154458-53-4 is a valid CAS Registry Number.
