Check Digit Verification of cas no

The CAS Registry Mumber 1037747-03-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,7,4 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1037747-03:
(9*1)+(8*0)+(7*3)+(6*7)+(5*7)+(4*4)+(3*7)+(2*0)+(1*3)=147
147 % 10 = 7
So 1037747-03-7 is a valid CAS Registry Number.

Direct C-2 arylation of alkyl 4-thiazolecarboxylates: New insights in synthesis of heterocyclic core of thiopeptide antibiotics

Martin, Thibaut,Verrier, Cecile,Hoarau, Christophe,Marsais, Francis

supporting information; experimental part, p. 2909 - 2912 (2009/05/30)

(Chemical Equation Presented) The Pd(0)-catalyzed regioselective C-2 (hetero)arylation of tert-butyl 4-thiazolecarboxylate with a broad (hetero)aryl halide is reported, including the direct coupling of pyridinyl halides. The process has allowed the preparation of valuable 2-pyridynyl-4- thiazolecarboxylates which are components of the complex heterocyclic core of thiopeptides antibiotics. As a first application, a synthesis of a tert-butyl sulfomycinamate thio-analogue from tert-butyl 4-thiazolecarboxylate is here described through a three-step direct pyridinylation, halogenation, and Stille cross-coupling sequence.
