Check Digit Verification of cas no

The CAS Registry Mumber 1284948-21-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,9,4 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1284948-21:
(9*1)+(8*2)+(7*8)+(6*4)+(5*9)+(4*4)+(3*8)+(2*2)+(1*1)=195
195 % 10 = 5
So 1284948-21-5 is a valid CAS Registry Number.

Photoredox-Catalyzed Dehydrogenative Csp3-Csp2Cross-Coupling of Alkylarenes to Aldehydes in Flow

Griffiths, Oliver M.,Esteves, Henrique A.,Chen, Yiding,Sowa, Karin,May, Oliver S.,Morse, Peter,Blakemore, David C.,Ley, Steven V.

, p. 13559 - 13571 (2021/10/01)

Executing photoredox reactions in flow offers solutions to frequently encountered issues regarding reproducibility, reaction time, and scale-up. Here, we report the transfer of a photoredox-catalyzed benzylic coupling of alkylarenes to aldehydes to a flow chemistry setting leading to improvements in terms of higher concentration, shorter residence times, better yields, ease of catalyst preparation, and enhanced substrate scope. Its applicability has been demonstrated by a multi-gram-scale reaction using high-power light-emitting diodes (LEDs), late-stage functionalization of selected active pharmaceutical ingredients (APIs), and also a photocatalyst recycling method.
