Check Digit Verification of cas no
The CAS Registry Mumber 342394-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,3,9 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 342394-00:
(8*3)+(7*4)+(6*2)+(5*3)+(4*9)+(3*4)+(2*0)+(1*0)=127
127 % 10 = 7
So 342394-00-7 is a valid CAS Registry Number.

A new facile synthesis of 2-aminothiazole-5-carboxylates
Zhao, Rulin,Gove, Stacey,Sundeen, Joseph E.,Chen, Bang-Chi
, p. 2101 - 2102 (2001)
A new facile method has been developed for the synthesis of 2-aminothiazole-5-carboxylates. The new method involves reaction of ethyl β-ethoxyacrylate with N-bromosuccinimide (NBS) to give a novel intermediate, α-bromo-α-formylacetate hemiacetal. Cyclization of the in situ formed hemiacetal with thioureas afforded 2-aminothiazole-5-carboxylates in 60-98% yields.
