139109-03-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139109-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139109-03:
(8*1)+(7*3)+(6*9)+(5*1)+(4*0)+(3*9)+(2*0)+(1*3)=118
118 % 10 = 8
So 139109-03-8 is a valid CAS Registry Number.

BIOSYNTHESIS OF CHEMICALLY DIVERSIFIED NON-NATURAL TERPENE PRODUCTS

-

Page/Page column 126, (2021/05/15)

The disclosure relates to compounds of the formulae (l)-(IV) and their use as substrates for making terpenoids. New substrates for terpene biosynthesis and methods for making new types of terpenes are described herein. Diterpenes occupy a unique molecular

N-GLYCOSYLATION OF PEPTIDES AND PROTEINS

-

Page/Page column 18, (2015/05/05)

A process for the production of a glycoconjugate by N-glycosylation of a protein or peptide comprising the sequence D/E-X-N-X-S/T, wherein each X is the same or different and is any natural amino acid other than proline, wherein the process comprises reacting the protein or peptide with a polyisoprenyl pyrophosphate of formula (I), or a salt thereof, in the presence of PglB: (I) to produce the glycoconjugate comprising the protein or peptide having a saccharide [SI] linked to the asparagine in the sequence D/E-X-N-X-S/T. Polyisoprenylpyrophosphates used as substrates in the biocatalytic process are also provided, as well as certain glycoconjugates.

Synthesis of isotopically labelled oligoprenyl diphosphates and their application in mechanistic investigations of terpene cyclases

Citron, Christian A.,Rabe, Patrick,Barra, Lena,Nakano, Chiaki,Hoshino, Tsutomu,Dickschat, Jeroen S.

, p. 7684 - 7691 (2015/04/22)

A flexible, efficient and robust method for the synthesis of isotopically labelled oligoprenyl diphosphates was developed. The method makes use of just a few building blocks (acetone, triethyl phosphonoacetate, and ethyl acetoacetate) from which several i
