Check Digit Verification of cas no

The CAS Registry Mumber 1185301-26-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,3,0 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1185301-26:
(9*1)+(8*1)+(7*8)+(6*5)+(5*3)+(4*0)+(3*1)+(2*2)+(1*6)=131
131 % 10 = 1
So 1185301-26-1 is a valid CAS Registry Number.

Preparation method of beta-homoglutamic acid

-

, (2020/11/05)

The invention belongs to the field of preparation of organic compounds, and provides a preparation method of beta-homoglutamic acid. The method is characterized in that: 3-cyclohexenecarboxylic acid is used as a raw material, beta-homoglutamic acid is synthesized at a high yield through three the steps of reactions of Curtius rearrangement, olefin oxidation and protection group removal, and beta-homoglutamic acid with high yield and high optical purity can be obtained through configuration retention by using optically pure 3-cyclohexenecarboxylic acid. The method has the advantages of easily available raw materials, mild reaction conditions and low cost, and is suitable for large-scale preparation of beta-homoglutamic acid.

Facile stereoselective synthesis of γ-substituted γ-amino acids from the corresponding α-amino acids

, p. 12867 - 12874 (2007/10/03)

A facile stereoselective method for the synthesis of γ-substituted, γ-amino acids from α-amino acids was developed. The key step of the procedure is complete reduction of the keto functionality of α-amino acyl Meldrum's acid by sodium acetoxyborohydride. The resulting amino alkyl Meldrum's acid undergoes thermal decarboxylative ring closure to a 5-substituted pyrrolidinone which yields the corresponding γ-amino acid after basic hydrolysis. The overall yield of the procedure ranges from 40 to 65%.
