132836-68-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132836-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,3 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132836-68:
(8*1)+(7*3)+(6*2)+(5*8)+(4*3)+(3*6)+(2*6)+(1*8)=131
131 % 10 = 1
So 132836-68-1 is a valid CAS Registry Number.

Substrate Acidities and Conversion Times for Reactions of Amides With Di-tert-butyl Dicarbonate

Hansen, Marvin M.,Harkness, Allen R.,Coffey, D. Scott,Bordwell, Frederick G.,Zhao, Yongyu

, p. 8949 - 8952 (1995)

The conversion time for 4-dimethylaminopyridine catalyzed reaction of amides with tert-butyl dicarbonate varies dramatically with substrate acidity.The pKa's in DMSO of some amides are determined to support correlation of reactivity with substr

Simple and efficient N-acylation reactions of chiral oxazolidinone auxiliaries

Ager, David J.,Allen, David R.,Schaad, David R.

, p. 1283 - 1285 (2007/10/03)

A simplified procedure for the N-acylation of oxazolidin-2-one chiral auxiliaries has been developed. The acylations occur at room temperature in the presence of triethylamine and catalytic quantities of 4-(N,N-dimethylamino)pyridine, thereby eliminating the necessity for a strong base such as butyllithium. Acylations with both symmetrical and mixed anhydrides, as well as acid chlorides, occur with a wide variety of oxazolidinone auxiliaries.
