1440425-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1440425-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,4,2 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1440425-52:
(9*1)+(8*4)+(7*4)+(6*0)+(5*4)+(4*2)+(3*5)+(2*5)+(1*2)=124
124 % 10 = 4
So 1440425-52-4 is a valid CAS Registry Number.
