Check Digit Verification of cas no

The CAS Registry Mumber 1254221-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1254221-40:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*2)+(3*1)+(2*4)+(1*0)=113
113 % 10 = 3
So 1254221-40-3 is a valid CAS Registry Number.

Palladium-Catalyzed Synthesis of Tetrasubstituted Olefins by Triple Domino Process

Naveen, Kanagaraj,Nikson, Savariyappan Albert,Perumal, Paramasivan Thirumalai

supporting information, p. 2407 - 2413 (2017/07/22)

An efficient, highly regio- and stereoselective protocol for the synthesis of tetrasubstituted olefins was developed to take place by a palladium(0)-catalyzed triple domino process. It involves the formation of three new C?C bonds through double carbopalladation and C?H activation across 2-bromoaryl alkynyl biaryls/heteroaryls with norbornene. This method is practically simple with broad substrate scope and tolerates a wide range of substituents. The products bearing 9H-pyrrolo[1,2-a]indole motifs reveal intriguing solid state fluorescence properties and thus form a new class of aggregation induced emission (AIE) fluorophores. (Figure presented.).

C-H bond functionalization in the synthesis of fused 1,2,3-triazoles

Panteleev, Jane,Geyer, Karolin,Aguilar-Aguilar, Angelica,Wang, Letian,Lautens, Mark

supporting information; experimental part, p. 5092 - 5095 (2011/02/22)

A highly modular approach to fused 1,2,3-triazoles has been developed featuring a one-pot procedure combining copper(I) catalyzed azide-alkyne cycloaddition and palladium-catalyzed C-H bond functionalization. A class of structurally unique heterocycles was synthesized in good yields.
