227312-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 227312-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,3,1 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 227312-12:
(8*2)+(7*2)+(6*7)+(5*3)+(4*1)+(3*2)+(2*1)+(1*2)=101
101 % 10 = 1
So 227312-12-1 is a valid CAS Registry Number.

An improved synthetic approach to thieno[2,3-d]-1,2,3-thiadiazole- carboxylates via diazotization of aminothiophene derivatives

Stanetty, Peter,Goerner, Erwin,Mihovilovic, Marko D.

, p. 761 - 765 (2007/10/03)

The common synthetic method for the synthesis of fused 1,2,3- thiadiazoles via diazotization is not generally applicable to aminothiophenes. A substantially improved experimental protocol for the preparation of the title compounds as a potential inducer of systemic acquired resistance in plants is reported based on a novel cyclization mechanism via a Huisgen-White type rearrangement.
