225502-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 225502-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,5,0 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 225502-77:
(8*2)+(7*2)+(6*5)+(5*5)+(4*0)+(3*2)+(2*7)+(1*7)=112
112 % 10 = 2
So 225502-77-2 is a valid CAS Registry Number.
