Check Digit Verification of cas no

The CAS Registry Mumber 1021700-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,7,0 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021700-90:
(9*1)+(8*0)+(7*2)+(6*1)+(5*7)+(4*0)+(3*0)+(2*9)+(1*0)=82
82 % 10 = 2
So 1021700-90-2 is a valid CAS Registry Number.

Samarium-mediated intramolecular cross-couplings of an α,β-unsaturated N-acylpyrrole

Law, Katherine R.,McErlean, Christopher S.P.

, p. 3113 - 3116 (2016)

The first example of an α,β-unsaturated N-acylpyrrole undergoing a SmI2-mediated cyclization is reported. In contrast to other unsaturated units, the intermediate samarium enolate readily engages in aldol-type reactions, necessitating careful control of the reaction conditions.

Stetter reactions of unsaturated 1-acyl-1H-pyrroles

Phippen, Christopher B. W.,Goldys, Anna M.,McErlean, Christopher S. P.

experimental part, p. 6957 - 6964 (2012/01/13)

α,β-Unsaturated 1-acyl-1H-pyrroles are employed as enabling units for the construction of 1,4-dicarbonyl systems using the organocatalytic Stetter reaction. The enhanced electrophilicity of the 1-acyl-1H-pyrrole unit allows for the catalytic construction of fused and non-fused pyranones from aliphatic aldehydes, is compatible with aromatic aldehydes, and also facilitates an intermolecular variant of the reaction involving both aromatic and aliphatic aldehydes.

Synthetic studies on maitotoxin. 2. Stereoselective synthesis of the WXYZA -ring system

Morita, Masayuki,Haketa, Tasuku,Koshino, Hiroyuki,Nakata, Tadashi

supporting information; experimental part, p. 1679 - 1682 (2009/04/12)

The stereoselective synthesis of the WXYZA -ring system of maitotoxin has been accomplished via a linear synthetic approach, in which key reactions were Sml2-induced cyclization of ss-alkoxyacrylate for the construction of the A -, Y-, and X-rings and 6-endo cyclization of hydroxy vinylepoxide for that of the Z- and W-rings.
