105519-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105519-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105519-75:
(8*1)+(7*0)+(6*5)+(5*5)+(4*1)+(3*9)+(2*7)+(1*5)=113
113 % 10 = 3
So 105519-75-3 is a valid CAS Registry Number.

Configurational Stability of N-Protected α-Amino Aldehydes
Lubell, William D.,Rapoport, Henry
, p. 236 - 239 (2007/10/02)
A three-step synthesis of N-(9-(9-phenylfluorenyl)-L-alaninal (5) from alanine is described.Exposure to silica or nonnucleophilic base causes no detectable racemization of this α-amino aldehyde.The 9-(9-phenylfluorenyl) N-protecting group also maintains t
