Check Digit Verification of cas no

The CAS Registry Mumber 260783-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,7,8 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 260783-80:
(8*2)+(7*6)+(6*0)+(5*7)+(4*8)+(3*3)+(2*8)+(1*0)=150
150 % 10 = 0
So 260783-80-0 is a valid CAS Registry Number.

Palladium-Catalyzed Reductive Aminocarbonylation of Benzylammonium Triflates with o-Nitrobenzaldehydes for the Synthesis of 3-Arylquinolin-2(1 H)-ones

Liu, Yongzhu,Qi, Xinxin,Wu, Xiao-Feng

, p. 13824 - 13832 (2021/10/12)

A palladium-catalyzed straightforward procedure for the synthesis of 3-arylquinolin-2(1H)-ones has been developed. The synthesis proceeds through a palladium-catalyzed reductive aminocarbonylation reaction of benzylic ammonium triflates with o-nitrobenzaldehydes, and a wide range of 3-arylquinolin-2(1H)-ones was obtained in moderate to good yields with very good functional group compatibility.

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

Cu2O-catalyzed C–S coupling of quaternary ammonium salts and sodium alkane-/arene-sulfinates

Chen, Hongyi,Huang, Youming,Zeng, Qingle,Zheng, Wenting

supporting information, (2020/08/28)

A new protocol for the synthesis of (enantioenriched) benzylic sulfones via the Cu2O-catalyzed C–S bond cross coupling of alkane-/arene-sulfinates and (enantioenriched) benzylic quaternary ammonium salts has been developed. The product benzylic sulfones were obtained in good to high yields (75–96%). Chiral arylmethyl sulfones with high enantiomeric excess (90–94% ee) were also synthesized in the presence of Cu2O and 1,1′-bis-(diphenylphosphino)ferrocene (dppf).
