1. 2-(2,3-Dichlorphenyl)-2-(guanidinylimino)acetonitrile (Lamotrigine EP Impurity C) is an intermediate in the synthesis of the drug Lamotrigine (L173250).
2. An intermediate in the synthesis of the drug Lamotrigine (L173250).

Check Digit Verification of cas no

The CAS Registry Mumber 84689-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,8 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84689-20:
(7*8)+(6*4)+(5*6)+(4*8)+(3*9)+(2*2)+(1*0)=173
173 % 10 = 3
So 84689-20-3 is a valid CAS Registry Number.
