Check Digit Verification of cas no

The CAS Registry Mumber 20511-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,1 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20511-12:
50 % 10 = 0
So 20511-12-0 is a valid CAS Registry Number.

Synthesis of 2,3-Disubstituted 5-Iodo-1H-Pyrrolo[2,3-b]pyridines via Fischer Cyclization

Alekseyev, Roman S.,Amirova, Sabina S.,Terenin, Vladimir I.

, p. 2656 - 2663 (2017)

A simple and convenient procedure for the preparation of some unknown 2,3-disubstituted 5-iodo-1H-pyrrolo[2,3-b]pyridines from readily available starting materials by Fischer indole cyclization in polyphosphoric acid is described. The present methodology provides an alternative synthetic approach to the synthesis of 5-iodo-7-azaindole scaffold. All synthesized compounds were characterized by IR, MS, 1H and 13C NMR, and elemental analysis.

Sulfated polyborate-H2O assisted tunable activation of N-iodosuccinimide for expeditious mono and diiodination of arenes

Misal, Balu,Palav, Amey,Ganwir, Prerna,Chaturbhuj, Ganesh

supporting information, (2021/05/26)

Owing to both Lewis and Bronsted acid active sites on sulfated polyborate under homogenous conditions, we were keen on developing iodination protocol of arenes that can meet the requirement of regioselectivity and higher yield. The sulfated polyborate activates N-iodosuccinimide for mono iodination of highly activated substrates viz. phenols, anilines under anhydrous condition. Water tunes sulfated polyborate to generate more Bronsted acid sites resulting in rapid activation of NIS for diiodination. The protocol was equally applicable to diiodination of 4-hydroxyphenylacetic acid to synthesize 4-hydroxy-3,5-diiodophenylacetic acid, an intermediate of tiratricol, a thyroid treatment drug. This protocol was further integrated via one-pot sequential iodination and Sonogashira coupling to synthesize aryl acetylenes, building blocks for the synthesis of a variety of specialty chemicals, API, and natural products.



Paragraph 613; 625, (2021/11/06)

The invention relates to kinase inhibitors, in particular inhibitors of protein kinases including the SIK-family, CSF1R, HCK, TEK-family, BRK, ABL, KIT and/or their mutants. Although structurally similar to other bicyclic kinase inhibitors, the kinase inhibitors of the invention are distinctive; possessing a particular class of heterocyclic moiety. Such kinase inhibitors can display one or more certain properties distinct to their structurally similar kinase inhibitors. The kinase inhibitors of the invention or pharmaceutical compositions comprising them may be used in the treatment of a disorder or condition, such as a proliferative disorder, for example, a leukaemia or solid tumour. In particular, these and other structurally related kinase inhibitors may be used in the treatment of a proliferative disorder - such as a mixed phenotype acute leukaemia (MPAL) - characterised by (inter-alia) the presence of MEF2C protein, a human chromosomal translocation at 11q23, and/or a KMT2A fusion oncoprotein. The kinase inhibitors or pharmaceutical compositions of the invention may be used topically to modulate skin pigmentation in a subject, for example to impart UV protection and reduce skin cancer risk.
