Check Digit Verification of cas no

The CAS Registry Mumber 642993-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,9,9 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 642993-67:
(8*6)+(7*4)+(6*2)+(5*9)+(4*9)+(3*3)+(2*6)+(1*7)=197
197 % 10 = 7
So 642993-67-7 is a valid CAS Registry Number.

General Asymmetric Synthetic Strategy for the α-Alkylated 2,5,6-Trisubstituted Pyran of Indanomycin and Related Natural Products

Mohapatra, Debendra K.,Padma, Ravishetty,Srinivas, Beduru,Yadav, Jhillu S.

, (2020/03/26)

A general synthetic strategy for convergent asymmetric synthesis of C1–C10 fragment of tetraene-containing natural product indanomycin was achieved starting from 2-(benzyloxy)acetaldehyde which in turn was obtained from very inexpensive material cis-1,4-butene-diol. Key steps include Evans' aldol reaction, HWE olefination, iodine-catalyzed tandem isomerization followed by C–O and C–C bond formation similar to our earlier report in constructing the trans-2,6-disubstituted dihydropyran ring and Evans' asymmetric alkylation.

Synthesis of a 35-member stereoisomer library of bistramide A: Evaluation of effects on actin state, cell cycle and tumor cell growth

supporting information; experimental part, p. 1897 - 1916 (2009/07/01)

Synthesis and preliminary biological evaluation of a 35-member library of bistramide A stereoisomers are reported. All eight stereoisomers of the C1-C13 tetrahydropyran fragment of the molecule were prepared utilizing crotylsilane reagents 9 and 10 in our

Synthesis of the C14-C25 Subunit of Bafilomycin A1

Eustache, Florence,Dalko, Peter I.,Cossy, Janine

, p. 9994 - 10002 (2007/10/03)

The enantioselective synthesis of the C14-C25 subunit of bafilomycin A 1, was realized in a convergent route. The sequence involves two dynamic kinetic resolution steps of 2-alkyl 1,3-diketones that use optically active ruthenium complexes, an

Enantioselective monoreduction of 2-alkyl 1,3-diketones using chiral ruthenium catalysts. Synthesis of the C14-C25 fragment of bafilomycin A 1

Eustache, Florence,Dalko, Peter I.,Cossy, Janine

, p. 8823 - 8826 (2007/10/03)

The enantioselective monoreduction of 2-alkyl 1,3-diketones by dynamic kinetic resolution using optically active ruthenium catalysts allowed the preparation of the C14-C25 fragment of bafilomycin A1.
