Check Digit Verification of cas no

The CAS Registry Mumber 166756-77-0 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 166756-77:
(8*1)+(7*6)+(6*6)+(5*7)+(4*5)+(3*6)+(2*7)+(1*7)=180
180 % 10 = 0
So 166756-77-0 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 (1995)

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.

Stereospecific Synthesis of 4-Alkylglutamates and 4-Alkylprolines

Moody, Claire M.,Young, Douglas W.

, p. 7277 - 7280 (2007/10/02)

Catalytic reduction of the 4-alkylidenepyroglutamate derivatives (3) affords an effective route to (2S,4S)-4-alkylglutamic acids and (2S,4S)-4-alkylprolines.The route has also been used to prepare a 4-alkylpyroglutamic acid derivative which is stereospeci
