40740-42-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40740-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40740-42:
(7*4)+(6*0)+(5*7)+(4*4)+(3*0)+(2*4)+(1*2)=89
89 % 10 = 9
So 40740-42-9 is a valid CAS Registry Number.
