Check Digit Verification of cas no
The CAS Registry Mumber 408533-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,5,3 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 408533-46:
(8*4)+(7*0)+(6*8)+(5*5)+(4*3)+(3*3)+(2*4)+(1*6)=140
140 % 10 = 0
So 408533-46-0 is a valid CAS Registry Number.
