224580-62-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 224580-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,5,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 224580-62:
(8*2)+(7*2)+(6*4)+(5*5)+(4*8)+(3*0)+(2*6)+(1*2)=125
125 % 10 = 5
So 224580-62-5 is a valid CAS Registry Number.
