Check Digit Verification of cas no

The CAS Registry Mumber 25409-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25409-22:
(7*2)+(6*5)+(5*4)+(4*0)+(3*9)+(2*2)+(1*2)=97
97 % 10 = 7
So 25409-22-7 is a valid CAS Registry Number.

A short synthesis of naturally occurring and other analogues of plakinic acids that contain the 1,2-dioxolane group

Bloodworth,Bothwell, Brian D.,Collins, Andrew N.,Maidwell, Nicola L.

, p. 1885 - 1888 (1996)

Natural and unnatural analogues 4 of plakinic acids A, C and D have been prepared in three steps from alkan-2-ones by (i) LDA-induced condensation with ethyl-3-methylbut-2-enoate to give (2Z)-3,5-dimethylalka-2,4-dienoic acids 10, then (ii) isomerisation to the 2E-isomers 5 and finally (iii) peroxymercuriation with 30% hydrogen peroxide and reduction in situ with sodium borohydride.

REFORMATSKY REACTION USING Zn/Ag COUPLE

Bortolussi, Michel,Seyden-Penne, Jacqueline

, p. 2355 - 2362 (2007/10/02)

The Reformatsky reaction is easy to run in ethereal solvents in the presence of Zn/Ag couple.From methyl γ-bromocrotonate and krtones, remified esters are fromed in refluxing Et2O, linear ones in refluxing THF.
