166756-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166756-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,7,5 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 166756-74:
(8*1)+(7*6)+(6*6)+(5*7)+(4*5)+(3*6)+(2*7)+(1*4)=177
177 % 10 = 7
So 166756-74-7 is a valid CAS Registry Number.

A Highly Diastereoselective Synthesis of 4-Alkyl Threo Glutamic Acids
Gu, Zi-Qiang,Hesson, David P.
, p. 2101 - 2104 (2007/10/03)
Treatment of N-p-nitrobenzoyl L- or D-glutamic acid diester with lithium bis(trimethylsilyl)amide generates a chelated γ-enolate which reacts with alkyl halides to give (2S,4S)- or (2R,4R)-4-alkylated glutamic acid derivatives with very high diastereoselectivity.
