259223-75-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 259223-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,2,2 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 259223-75:
(8*2)+(7*5)+(6*9)+(5*2)+(4*2)+(3*3)+(2*7)+(1*5)=151
151 % 10 = 1
So 259223-75-1 is a valid CAS Registry Number.
