616867-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 616867-25-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,6,8,6 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 616867-25:
(8*6)+(7*1)+(6*6)+(5*8)+(4*6)+(3*7)+(2*2)+(1*5)=185
185 % 10 = 5
So 616867-25-5 is a valid CAS Registry Number.

A stereodivergent approach to chiral nonracemic N-protected α,α-dialkylated amino acids
Spino, Claude,Gobdout, Cedrickx
, p. 12106 - 12107 (2007/10/03)
Menthyl carboxaldehyde is used as a chiral auxiliary to make quaternary amino acids of either configuration via a stereodivergent approach that includes an SN2′ displacement by a cuprate reagent and a Curtius rearrangement as key steps. Copyright
