Check Digit Verification of cas no

The CAS Registry Mumber 20268-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20268-21:
(7*2)+(6*0)+(5*2)+(4*6)+(3*8)+(2*2)+(1*1)=77
77 % 10 = 7
So 20268-21-7 is a valid CAS Registry Number.

Titanium(IV)chloride-triethylsilane mediated conversion of ν-nitrostyrenes to phenylacetohydroximoyl chlorides

Kumaran,Kulkarni, Gurunath H.

, p. 9099 - 9100 (1994)

A novel methodology for hitherto unknown phenylacetohydroximoyl chlorides from ν-nitrostyrenes by reaction with TiCl4-Et3SiH is reported.

Improved Synthesis of Glucosinolates

Lim, Yi Wee,Ong, Michelle Jui Hsien,Hewitt, Russell J.

, p. 1640 - 1650 (2018/02/06)

Herein we describe an improved synthesis of glucosinolates, in which the quantity and cost of materials have been reduced by approximately an order of magnitude compared to typical literature procedures. This allowed us to produce multiple glucosinolates in 10-25 gram batches using vessel sizes no larger than 0.5 litres.

New approach to oximes through reduction of nitro compounds enabled by visible light photoredox catalysis

Cai, Shunyou,Zhang, Shaolong,Zhao, Yaohong,Wang, David Zhigang

, p. 2660 - 2663 (2013/07/11)

A range of nitro compounds are smoothly reduced to their corresponding oximes under the synergistic effects of visible light irradiation, the Ru(bpy)3Cl2 photocatalyst, Hünig's base, Mg(ClO 4)2 activation, and MeCN solvent. This remarkably mild and environmentally benign protocol, when orchestrated with classical Beckmann rearrangement, enables such high-value industrial feedstock as caprolactam to be readily accessed from simple precursor nitrocyclohexane.
