425392-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 425392-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,3,9 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 425392-51:
(8*4)+(7*2)+(6*5)+(5*3)+(4*9)+(3*2)+(2*5)+(1*1)=144
144 % 10 = 4
So 425392-51-4 is a valid CAS Registry Number.
