The CAS Registry Mumber 140458-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140458-20:
(8*1)+(7*4)+(6*0)+(5*4)+(4*5)+(3*8)+(2*2)+(1*0)=104
104 % 10 = 4
