Check Digit Verification of cas no

The CAS Registry Mumber 847834-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,8,3 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 847834-43:
(8*8)+(7*4)+(6*7)+(5*8)+(4*3)+(3*4)+(2*4)+(1*3)=209
209 % 10 = 9
So 847834-43-9 is a valid CAS Registry Number.

Green organocatalytic synthesis of isoxazolines via a one-pot oxidation of allyloximes

Triandafillidi, Ierasia,Kokotos, Christoforos G.

, p. 106 - 109 (2017/11/27)

A green, sustainable, organocatalytic, and efficient synthesis of isoxazolines from allyloximes was developed. A 2,2,2-trifluoroacetophenone-catalyzed oxidation of allyloximes, utilizing H2O2 as the green oxidant, was taken advantage of in order to introduce a cheap and environmentally friendly protocol for the synthesis of substituted isoxazolines. A variety of substitution patterns, both aromatic and aliphatic moieties, are well tolerated, leading to isoxazolines in moderate to excellent yields.

One-pot cyclizations of dilithiated oximes and hydrazones with epibromohydrin. Efficient synthesis of 6-hydroxymethyl-5,6-dihydro-4H-1,2- oxazines and oxazolo[3,4-b]pyridazin-7-ones

Dang, Tuan Thanh,Albrecht, Uwe,Gerwien, Katrin,Siebert, Melanie,Langer, Peter

, p. 2293 - 2301 (2007/10/03)

The one-pot cyclization of dilithiated oximes with epibromohydrin provided a convenient and regioselective approach to 6-hydroxymethyl-5,6-dihydro-4H-1,2- oxazines. The reaction of the latter with phosphorus tribromide resulted in a Beckmann rearrangement
