The CAS Registry Mumber 31640-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,4 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31640-43:
(7*3)+(6*1)+(5*6)+(4*4)+(3*0)+(2*4)+(1*3)=84
84 % 10 = 4
