111652-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111652-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111652-16:
(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*2)+(2*1)+(1*6)=85
85 % 10 = 5
So 111652-16-5 is a valid CAS Registry Number.

Synthesis of α-Amino Acids by Reaction of t-Butyl N-(t-Butoxycarbonyl)iminoacetate With C-Nucleophiles
Muenster, Peter,Steglich, Wolfgang
, p. 223 - 225 (2007/10/02)
The reaction of t-butyl N-(t-butoxycarbonyl)iminoacetate with Grignard reagents or enamines yields N-(t-butoxycarbonyl)amino acid t-butyl esters which can be easily converted into the free amino acids by treatment with acids.
