463965-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 463965-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,3,9,6 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 463965-24:
(8*4)+(7*6)+(6*3)+(5*9)+(4*6)+(3*5)+(2*2)+(1*4)=184
184 % 10 = 4
So 463965-24-4 is a valid CAS Registry Number.
