55881-64-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55881-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,8 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55881-64:
156 % 10 = 6
So 55881-64-6 is a valid CAS Registry Number.

Substituent-controlled annuloselectivity and stereoselectivity in the sulfa-Staudinger cycloadditions

Yang, Zhanhui,Chen, Ning,Xu, Jiaxi

, p. 3611 - 3620 (2015/04/22)

In the sulfa-Staudinger cycloadditions of imines and sulfonyl chlorides, the annuloselectivity is mainly controlled by the electronic effect of the α-substituents of sulfonyl chlorides and the nucleophilicity of imines. Sulfonyl chlorides with weakly elec

Synthesis and Configuration of 4-Alkyl-2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-Dioxide

Grunder, Evelyne,Leclerc, Gerard,Ehrhardt, Jean-Daniel

, p. 1781 - 1785 (2007/10/02)

4-Alkyl-2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-dioxide 5, 6 and 7 were obtained from 2-methyl-3,4-diphenyl-1,2-thiazetidine 1,1-dioxide 1 by reaction of its anion 4 with alkyl halides. cis- and trans-Configuration of 4-alkylated products were determined by 1H-nmr and NOE difference spectroscopy studies.
