1427321-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1427321-54-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,3,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1427321-54:
(9*1)+(8*4)+(7*2)+(6*7)+(5*3)+(4*2)+(3*1)+(2*5)+(1*4)=137
137 % 10 = 7
So 1427321-54-7 is a valid CAS Registry Number.

Synthesis of functionalized allenamides from ynamides by enolate claisen rearrangement
Brioche, Julien,Meyer, Christophe,Cossy, Janine
, p. 1626 - 1629 (2013)
The Claisen rearrangement of N-Boc glycinates derived from ynamido-alcohols affords an efficient and stereoselective access to highly functionalized allenamides. These compounds undergo silver-catalyzed cyclization to 3-pyrrolines which are useful precurs
