256507-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 256507-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,5,0 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 256507-25:
(8*2)+(7*5)+(6*6)+(5*5)+(4*0)+(3*7)+(2*2)+(1*5)=142
142 % 10 = 2
So 256507-25-2 is a valid CAS Registry Number.
