Check Digit Verification of cas no

The CAS Registry Mumber 1416982-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,9,8 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1416982-07:
(9*1)+(8*4)+(7*1)+(6*6)+(5*9)+(4*8)+(3*2)+(2*0)+(1*7)=174
174 % 10 = 4
So 1416982-07-4 is a valid CAS Registry Number.

Palladium-Catalyzed C-N Cross-Coupling of NH-Heteroarenes and Quaternary Ammonium Salts via C-N Bond Cleavage

Chen, Hongyi,Yang, Hongqin,Li, Nutao,Xue, Xinghua,He, Ze,Zeng, Qingle

, p. 1679 - 1685 (2019)

In this paper, we extend the substrate class of Buchwald-Hartwig amination to quaternary ammonium salts. In the presence of Pd(OAc)2 and t-BuXPhos, the coupling of aryl- or arylmethyltrimethylammonium triflates with NH-heteroarenes via C-N bond cleavage affords the desired N-aryl or N-arylmethyl heteroarenes in moderate to excellent yields.

Synthesis of Dibenzylic Diselenides from Elemental Selenium and Benzylic Quaternary Ammonium Salts

Chen, Feng,Li, Fuhai,Zeng, Qingle

supporting information, p. 5605 - 5608 (2021/11/11)

Abstract: Substituted dibenzyl diselenides are synthesized in good yields (74–91 %) by SN2 nucleophilic substitution of benzylic trimethylammonium salts and diselenide dianion (Se2?), in situ generated from elemental selenium, under

Transition metal-free coupling reactions of benzylic trimethylammonium salts with di(hetero)aryl disulfides and diselenides

Li, Fuhai,Wang, Dan,Chen, Hongyi,He, Ze,Zhou, Lihong,Zeng, Qingle

supporting information, p. 13029 - 13032 (2020/11/07)

A new protocol was developed to synthesize (enantioenriched) thioethers and selenoethers from (chiral) benzylic trimethylammonium salts and di(hetero)aryl disulfides or diselenides. These syntheses were promoted by the presence of weak base and did not require the use of any transition metal, and resulted in the target products with good to excellent yields (72-94%). Using quaternary ammonium salts synthesized from enantiomerically enriched amines led to highly enantiopure benzylic thioethers and selenoethers (94-99% ee) with configurations reversed from those of their enantioenriched quaternary ammonium salts.
