1358895-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1358895-33-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,8,8,9 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1358895-33:
(9*1)+(8*3)+(7*5)+(6*8)+(5*8)+(4*9)+(3*5)+(2*3)+(1*3)=216
216 % 10 = 6
So 1358895-33-6 is a valid CAS Registry Number.

Synthesis of perhydrofuro[2,3-b]furans from isopentenyl alcohol through carbonyl-ene and wacker-type reactions

Alonso, Francisco,Rodriguez-Fernandez, Mamen,Sanchez, Daniel,Yus, Miguel

, p. 6459 - 6469 (2011)

A range of 2-substituted perhydrofuro[2,3-b]furans have been synthesized in a stereoselective manner through a sequence involving the Lewis-acid catalyzed carbonyl-ene reaction of a protected isopentenyl alcohol with a variety of enophiles, deprotection of the corresponding monoprotected diols, and palladium-catalyzed intramolecular acetalization under Wacker-type reaction conditions. A new synthetic approach toward the synthesis of perhydrofuro[2,3-b]furans is described. The strategy is based on the carbonyl-ene reaction for a protected isopentenyl alcohol with several activated enophiles followed by deprotection and palladium-catalyzed intramolecular acetalization.
