251997-46-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251997-46-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,9 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 251997-46:
(8*2)+(7*5)+(6*1)+(5*9)+(4*9)+(3*7)+(2*4)+(1*6)=173
173 % 10 = 3
So 251997-46-3 is a valid CAS Registry Number.
