Check Digit Verification of cas no

The CAS Registry Mumber 2161-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2161-68:
(6*2)+(5*1)+(4*6)+(3*1)+(2*6)+(1*8)=64
64 % 10 = 4
So 2161-68-4 is a valid CAS Registry Number.

Structure-based design of highly selective 2,4,5-trisubstituted pyrimidine CDK9 inhibitors as anti-cancer agents

Shao, Hao,Foley, David W.,Huang, Shiliang,Abbas, Abdullahi Y.,Lam, Frankie,Gershkovich, Pavel,Bradshaw, Tracey D.,Pepper, Chris,Fischer, Peter M.,Wang, Shudong

Cyclin-dependent kinases (CDKs) are a family of Ser/Thr kinases involved in cell cycle and transcriptional regulation. CDK9 regulates transcriptional elongation and this unique property has made it a potential target for several diseases. Due to the conserved ATP binding site, designing selective CDK9 inhibitors has been challenging. Here we report our continued efforts in the optimization of 2,4,5-tri-substituted pyrimidine compounds as potent and selective CDK9 inhibitors. The most selective compound 30m was >100-fold selective for CDK9 over CDK1 and CDK2. These compounds showed broad anti-proliferative activities in various solid tumour cell lines and patient-derived chronic lymphocytic leukaemia (CLL) cells. Decreased phosphorylation of the carboxyl terminal domain (CTD) of RNAPII at Ser-2 and down-regulation of anti-apoptotic protein Mcl-1 were confirmed in both the ovarian cancer model A2780 and patient-derived CLL cells.

Paragraph 0022, (2017/10/05)

The invention discloses a method for preparing such CDK inhibitors, will be single-methyl thiourea and 1 - N monochloride reaction, 4 - dimethylthiazole - 2 - amine, by bromo reaction to obtain 5 - bromo - N, 4 - dimethylthiazole - 2 - amine, under the action of the catalyst after the with the borate to obtain aromatic borate intermediates; aromatic borate ester intermediate with 2, 4 - dichloro - 5 fluoro uracil in the noble metal catalytic under suzuki coupling reaction to obtain the coupling product to continue after the Buchwald - Hartwig with the aromatic amine in the reaction, ultimately to obtain the target product.

Domino alkylation-cyclization reaction of propargyl bromides with thioureas/thiopyrimidinones: A new facile synthesis of 2-aminothiazoles and 5H-thiazolo[3,2-α]pyrimidin-5-ones

Castagnolo, Daniele,Pagano, Mafalda,Bernardini, Martina,Botta, Maurizio

experimental part, p. 2093 - 2096 (2011/04/15)

A new synthesis of 2-aminothiazoles and 5H-thiazolo[ 3,2-α]pyrimidin- 5-ones was developed as a domino alkylation-cyclization reaction of propargyl bromides with thioureas and thiopyrimidinones, respectively. Domino reactions were performed under microwave irradiation leading to desired compounds in a few minutes and high yields. Georg Thieme Verlag Stuttgart.
