23912-86-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23912-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,1 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 23912-86:
(7*2)+(6*3)+(5*9)+(4*1)+(3*2)+(2*8)+(1*6)=109
109 % 10 = 9
So 23912-86-9 is a valid CAS Registry Number.

Poly(ethylene glycol)- and glucopyranoside-substituted N-heterocyclic carbene precursors for the synthesis of arylfluorene derivatives using efficient palladium-catalyzed aqueous Suzuki reaction

Zhou, Zhonggao,Zhao, Yan,Zhen, Hongyu,Lin, Zhenghuan,Ling, Qidan

, p. 924 - 931 (2016)

This paper reports an environmentally friendly and highly efficient synthesis of organic semiconductor materials via a Pd/N-heterocyclic carbene (NHC)-catalyzed Suzuki reaction in aqueous ethanol with high isolated yields (86–98%). Firstly, four glucopyra

Green, Efficient and Reusable Bis(imidazolium) Ionic Liquids Promoted Pd-Catalyzed Aqueous Suzuki Reaction for Organic Functional Materials

Zhou, Zhonggao,Yuan, Yangyang,Xie, Yongrong,Li, Mei

, p. 2696 - 2702 (2018/07/13)

Abstract: Glucopyranoside-substituted asymmetric bis(imidazolium) ionic liquids were used to promote environmentally friendly, efficient and reusable Pd-catalyzed Suzuki reaction between arylboronic acids and 2-bromofluorene, 2,7-dibromo-9,9′-dialkylfluorene. Over 30 carbazole-based fluorene core potential organic functional materials were synthesized. In addition, recyclability of catalyst system was inspected on the Suzuki reaction observing nearly no loss in catalytic activity up to five cycles. Graphical Abstract: Development of green, efficient and recycle glucopyranoside substituted bis(imidazolium) ILs promoted Pd-catalyzed aqueous Suzuki reaction for OFMs. [Figure not available: see fulltext.].
