Check Digit Verification of cas no

The CAS Registry Mumber 1417652-41-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,6,5 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1417652-41:
(9*1)+(8*4)+(7*1)+(6*7)+(5*6)+(4*5)+(3*2)+(2*4)+(1*1)=155
155 % 10 = 5
So 1417652-41-5 is a valid CAS Registry Number.

Synthesis of ortho/ortho ′-substituted 1,1-diarylethylenes through cross-coupling reactions of sterically encumbered hydrazones and aryl halides

Roche, Maxime,Hamze, Abdallah,Provot, Olivier,Brion, Jean-Daniel,Alami, Mouad

, p. 445 - 454 (2013/03/13)

The reactivity of sterically hindered N-tosylhydrazones 2 featuring ortho/ortho′-substituents on the aromatic ring with various ortho-, meta-, and para-substituted aryl halides 3 was investigated. To accomplish successfully this challenging coupling, fine-tuning of the reaction conditions were required. The newly established PdCl2(MeCN)2/Xphos/ NaO-t-Bu/F-benzene system in a sealed tube is compatible with a broad spectrum of both coupling partners, regardless of their electronic and steric nature. This protocol has been applied successfully to the synthesis of a xanthene derivative.
