451495-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 451495-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,1,4,9 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 451495-66:
(8*4)+(7*5)+(6*1)+(5*4)+(4*9)+(3*5)+(2*6)+(1*6)=162
162 % 10 = 2
So 451495-66-2 is a valid CAS Registry Number.
