225658-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 225658-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,6,5 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 225658-24:
(8*2)+(7*2)+(6*5)+(5*6)+(4*5)+(3*8)+(2*2)+(1*4)=142
142 % 10 = 2
So 225658-24-2 is a valid CAS Registry Number.
