450409-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 450409-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,4,0 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 450409-34:
(8*4)+(7*5)+(6*0)+(5*4)+(4*0)+(3*9)+(2*3)+(1*4)=124
124 % 10 = 4
So 450409-34-4 is a valid CAS Registry Number.
