140458-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140458-75-9 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, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 140458-75:
(8*1)+(7*4)+(6*0)+(5*4)+(4*5)+(3*8)+(2*7)+(1*5)=119
119 % 10 = 9
So 140458-75-9 is a valid CAS Registry Number.
