Check Digit Verification of cas no

The CAS Registry Mumber 18209-98-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18209-98:
(7*1)+(6*8)+(5*2)+(4*0)+(3*9)+(2*9)+(1*8)=118
118 % 10 = 8
So 18209-98-8 is a valid CAS Registry Number.

Photoredox-Catalyzed Four-Component Reaction for the Synthesis of Complex Secondary Amines

Kammer, Lisa Marie,Krumb, Matthias,Spitzbarth, Benjamin,Lipp, Benjamin,Kühlborn, Jonas,Busold, Jonas,Mulina, Olga M.,Terentev, Alexander O.,Opatz, Till

, p. 3318 - 3322 (2020)

The one-pot sulfonylation/aminoalkylation of styrene derivatives furnishing substituted ?3-sulfonylamines was accomplished through a photoredox-catalyzed four-component reaction. Besides one molecule of water and the sodium counterion of the sulfinate, all atoms of the starting materials are transferred to the final product, rendering this process highly atom-efficient. The operationally simple protocol allows for the simultaneous formation of three new single bonds (C-S, C-N, and C-C) and therefore grants rapid access to structurally diverse products.
