Check Digit Verification of cas no

The CAS Registry Mumber 189635-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189635-01:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*5)+(2*0)+(1*1)=176
176 % 10 = 6
So 189635-01-6 is a valid CAS Registry Number.

Discovery of β-Arrestin Biased, Orally Bioavailable, and CNS Penetrant Neurotensin Receptor 1 (NTR1) Allosteric Modulators

Pinkerton, Anthony B.,Peddibhotla, Satyamaheshwar,Yamamoto, Fusayo,Slosky, Lauren M.,Bai, Yushi,Maloney, Patrick,Hershberger, Paul,Hedrick, Michael P.,Falter, Bekhi,Ardecky, Robert J.,Smith, Layton H.,Chung, Thomas D. Y.,Jackson, Michael R.,Caron, Marc G.,Barak, Lawrence S.

Neurotensin receptor 1 (NTR1) is a G protein coupled receptor that is widely expressed throughout the central nervous system where it acts as a neuromodulator. Neurotensin receptors have been implicated in a wide variety of CNS disorders, but despite extensive efforts to develop small molecule ligands there are few reports of such compounds. Herein we describe the optimization of a quinazoline based lead to give 18 (SBI-553), a potent and brain penetrant NTR1 allosteric modulator.

Pd-Catalyzed tandem reaction of N-(2-cyanoaryl)benzamides with arylboronic acids: synthesis of quinazolines

Zhu, Jianghe,Shao, Yinlin,Hu, Kun,Qi, Linjun,Cheng, Tianxing,Chen, Jiuxi

supporting information, p. 8596 - 8603 (2018/11/27)

The synthesis of 2,4-disubstituted quinazolines by a palladium-catalyzed reaction of arylboronic acids with N-(2-cyanoaryl)benzamides has been developed with moderate to excellent yields. The method shows good functional group tolerance. In particular, ha
