The CAS Registry Mumber 74040-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,4 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74040-80:
(7*7)+(6*4)+(5*0)+(4*4)+(3*0)+(2*8)+(1*0)=105
