117770-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117770-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,7 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117770-95:
(8*1)+(7*1)+(6*7)+(5*7)+(4*7)+(3*0)+(2*9)+(1*5)=143
143 % 10 = 3
So 117770-95-3 is a valid CAS Registry Number.

NEW SYNTHESIS OF PROTECTED α-DEHYDRO α-AMINOACIDS FROM SUBSTITUTED OXAMIC ACID
Bazureau, J. P.,Le Corre, M.
, p. 1919 - 1920 (2007/10/02)
The condensation of a phosphorus ylid with t-butoxalyl iminoether gives 3-carbobutoxy 2-aza 1,3-dienes ; subsequent reaction with hydriodic acid provides protected α-dehydro α-amino acids.
