871266-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871266-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,2,6 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 871266-93:
(8*8)+(7*7)+(6*1)+(5*2)+(4*6)+(3*6)+(2*9)+(1*3)=192
192 % 10 = 2
So 871266-93-2 is a valid CAS Registry Number.

Single-step syntheses of 2-amino-7-chlorothiazolo[5,4-d]pyrimidines: Intermediates for bivalent thiazolopyrimidines
Liu, Jian,Patch, Raymond J.,Schubert, Carsten,Player, Mark R.
, p. 10194 - 10197 (2007/10/03)
A single-step process for the preparation of 2-amino-7-chlorothiazolo[5,4- d]pyrimidines, 2, was achieved by the reaction of the commercially available 4,6-dichloro-5-aminopyrimidine 1 with isothiocyanates. This mild reaction accommodates a variety of fun
