142465-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142465-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,6 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142465-20:
(8*1)+(7*4)+(6*2)+(5*4)+(4*6)+(3*5)+(2*2)+(1*0)=111
111 % 10 = 1
So 142465-20-1 is a valid CAS Registry Number.
