Check Digit Verification of cas no

The CAS Registry Mumber 200803-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,8,0 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 200803-17:
(8*2)+(7*0)+(6*0)+(5*8)+(4*0)+(3*3)+(2*1)+(1*7)=74
74 % 10 = 4
So 200803-17-4 is a valid CAS Registry Number.

Transition-Metal-Free Stereospecific Oxidative Annulative Coupling of Indolines with Aziridines

Karjee, Pallab,Sarkar, Tanumay,Kar, Subhradeep,Punniyamurthy, Tharmalingam

, p. 8261 - 8270 (2020/07/25)

Tandem C-N bond formation for the oxidative annulation of indolines with aziridines is accomplished employing the combination of DDQ and NaOCl at ambient conditions. Optically active aziridine can be coupled with high enantiomeric purity (>99% ee). The substrate scope, stereocontrol with the enantioenriched substrate, and scale-up are the important practical advantages.
