253445-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253445-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,4,4 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 253445-71:
(8*2)+(7*5)+(6*3)+(5*4)+(4*4)+(3*5)+(2*7)+(1*1)=135
135 % 10 = 5
So 253445-71-5 is a valid CAS Registry Number.
