463954-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 463954-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,3,9,5 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 463954-80:
(8*4)+(7*6)+(6*3)+(5*9)+(4*5)+(3*4)+(2*8)+(1*0)=185
185 % 10 = 5
So 463954-80-5 is a valid CAS Registry Number.
