13318-11-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13318-11-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,1 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13318-11:
(7*1)+(6*3)+(5*3)+(4*1)+(3*8)+(2*1)+(1*1)=71
71 % 10 = 1
So 13318-11-1 is a valid CAS Registry Number.

A convenient preparation of di-p-chlorobenzyl azodicarboxylate (DCAD) for mitsunobu couplings

Taft, Benjamin R.,Swift, Elizabeth C.,Lipshutz, Bruce H.

, p. 332 - 334 (2009)

Gram-scale synthesis of pure, bench-stable solid di-p-chlorobenzyl azodicarboxylate (DCAD) is performed in two steps without resorting to chromatography. This novel reagent effects Mitsunobu couplings with yields comparable to DEAD or DIAD, while addressi

METHOD FOR PRODUCING GLYCIDYL ESTER

-

Paragraph 0032; 0034-0038, (2017/11/09)

PROBLEM TO BE SOLVED: To provide a production method which makes it possible to obtain glycidyl ester with high yields from the ester exchange reaction between ester and glycidol with a convenient catalyst in a mild reaction condition. SOLUTION: Glycidyl ester is produced by the ester exchange reaction between ester and glycidol in the presence of a polystyrene-carrying quaternary ammonium salt.

Regioselective opening of an oxirane system with trifluoroacetic anhydride. A general method for the synthesis of 2-monoacyl- and 1,3-symmetrical triacylglycerols

Stamatov, Stephan D.,Stawinski, Jacek

, p. 3659 - 3669 (2007/10/03)

A trifluoroacetic anhydride-catalyzed opening of the oxirane system of glycidyl esters with a simultaneous migration of the acyl group provides a new, efficient entry to either 2-monoacylglycerols (2-MAG) or 1,3-symmetrical triglycerides (1,3-STG) as potential prodrug frameworks.
