Check Digit Verification of cas no
The CAS Registry Mumber 40618-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,1 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40618-31:
(7*4)+(6*0)+(5*6)+(4*1)+(3*8)+(2*3)+(1*1)=93
93 % 10 = 3
So 40618-31-3 is a valid CAS Registry Number.
