26476-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26476-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,7 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 26476-24:
(7*2)+(6*6)+(5*4)+(4*7)+(3*6)+(2*2)+(1*4)=124
124 % 10 = 4
So 26476-24-4 is a valid CAS Registry Number.

Process for the preparation of dichloroisonitrilocarboxylic acid esters
-
, (2008/06/13)
It is suggested to produce 5-chloro-1H-tetrazolecarboxylic acid esters by reaction of dichloroisonitriloacetic acid esters with alkali or metal azides or ammonium azide. The dichloroisonitriloacetic acid esters required for this purpose are formed by reacting N-formylaminocarboxylic acid esters with chlorine or with compounds which split off chlorine.
