23490-87-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23490-87-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23490-87:
(7*2)+(6*3)+(5*4)+(4*9)+(3*0)+(2*8)+(1*7)=111
111 % 10 = 1
So 23490-87-1 is a valid CAS Registry Number.
