Check Digit Verification of cas no

The CAS Registry Mumber 2223-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2223-71:
(6*2)+(5*2)+(4*2)+(3*3)+(2*7)+(1*1)=54
54 % 10 = 4
So 2223-71-4 is a valid CAS Registry Number.

Construction of Distant Stereocenters by Enantioselective Desymmetrizing Carbonyl-Ene Reaction

Luo, Weiwei,Lin, Lili,Zhang, Yu,Liu, Xiaohua,Feng, Xiaoming

, p. 3374 - 3377 (2017/07/15)

An efficient desymmetrizing carbonyl-ene reaction of 1-substituted 4-methylenecyclohexanes with glyoxal derivatives was thus executed by a chiral N,N′-dioxide/NiII catalyst, providing facile access to cyclohexene derivatives bearing two remote 1,6-related stereocenters. This distal stereocontrol methodology originates from the efficient interaction between the catalyst with enophiles, discrimination of the two chair conformations of olefinic components, and the intrinsic six-membered transition-state structure of ene process.

A remarkable iodine-catalyzed protection of carbonyl compounds

Banik, Bimal K.,Chapa, Marin,Marquez, Jocabed,Cardona, Magda

, p. 2341 - 2343 (2007/10/03)

We report here a remarkably simple molecular iodine-catalyzed protection method for various carbonyl compounds as ketals in a general reaction. The iodine-catalyzed reaction of mandelic acid and lactic acid with several aldehydes has furnished a highly diastereoselective synthesis of cis and trans dioxolanones.

An efficient procedure for the preparation of cyclic ketals and thioketals catalyzed by zirconium sulfophenyl phosphonate

Curini,Epifano,Marcotullio,Rosati

, p. 1182 - 1184 (2007/10/03)

A convenient method for the preparation of cyclic ketals and thioketals using zirconium sulfophenyl phosphonate as catalyst is described.
