140424-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140424-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,2 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140424-72:
(8*1)+(7*4)+(6*0)+(5*4)+(4*2)+(3*4)+(2*7)+(1*2)=92
92 % 10 = 2
So 140424-72-2 is a valid CAS Registry Number.
