3899-32-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3899-32-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3899-32:
(6*3)+(5*8)+(4*9)+(3*9)+(2*3)+(1*2)=129
129 % 10 = 9
So 3899-32-9 is a valid CAS Registry Number.

Rerouting and Improving Dauc-8-en-11-ol Synthase from Streptomyces venezuelae to a High Yielding Biocatalyst

Lauterbach, Lukas,Hou, Anwei,Dickschat, Jeroen S.

, p. 7923 - 7929 (2021/04/21)

The dauc-8-en-11-ol synthase from Streptomyces venezuelae was investigated for its catalytic activity towards alternative terpene precursors, specifically designed to enable new cyclisation pathways. Exchange of aromatic amino acid residues at the enzyme surface by site-directed mutagenesis led to a 4-fold increase of the yield in preparative scale incubations, which likely results from an increased enzyme stability instead of improved enzyme kinetics.

Synthesis of teleocidins A, B and their congeners. Part 3. Synthesis of dihydroteleocidin B-4 (dihydroteleocidin B), teleocidin B-3 and teleocidin B-4

Okabe, Kazuaki,Muratake, Hideaki,Natsume, Mitsutaka

, p. 8559 - 8572 (2007/10/02)

Details of the synthesis method of the tumor promoters teleocidin B-3 (3), teleocidin B-4 (4) and dihydroteleocidin B-4 (9) (=dihydroteleocidin B) from (S)- and (R)-methyl N-methyl-N-[7-(3,6,7-trimethyl-1,6-octadien-3-yl)-4-indolyl]-L-valinates (20b and 20a) are presented.
