250138-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 250138-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,1,3 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 250138-83:
(8*2)+(7*5)+(6*0)+(5*1)+(4*3)+(3*8)+(2*8)+(1*3)=111
111 % 10 = 1
So 250138-83-1 is a valid CAS Registry Number.
