7637-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7637-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7637-33:
(6*7)+(5*6)+(4*3)+(3*7)+(2*3)+(1*3)=114
114 % 10 = 4
So 7637-33-4 is a valid CAS Registry Number.

Continuous flow enables metallaphotoredox catalysis in a medicinal chemistry setting: Accelerated optimization and library execution of a reductive coupling between benzylic chlorides and aryl bromides

Brill, Zachary G.,Ritts, Casey B.,Mansoor, Umar Faruk,Sciammetta, Nunzio

supporting information, p. 410 - 416 (2020/01/21)

Continuous flow has been used widely in process chemistry and academic settings for various applications. However, initial reaction discovery has generally remained "batch-exclusive" despite the existence of efficient, reproducible flow systems. We hereby disclose a workflow to bridge the gap between early medicinal chemistry efforts and process-scale development, showcased by the discovery and optimization of a metallaphotoredox-catalyzed cross-coupling between benzylic chlorides and aryl bromides, followed by two library syntheses of complex drug-like compounds.
