430459-93-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 430459-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,0,4,5 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 430459-93:
(8*4)+(7*3)+(6*0)+(5*4)+(4*5)+(3*9)+(2*9)+(1*3)=141
141 % 10 = 1
So 430459-93-1 is a valid CAS Registry Number.
