144242-01-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144242-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144242-01:
(8*1)+(7*4)+(6*4)+(5*2)+(4*4)+(3*2)+(2*0)+(1*1)=93
93 % 10 = 3
So 144242-01-3 is a valid CAS Registry Number.

NHC-Mediated Synthesis of Tricyclic Spirocarbocycles via an Intramolecular Stetter Reaction of Cyclic Enal-Enones

Hsu, Day-Shin,Liang, Suz-Ping

, p. 1270 - 1278 (2019/12/30)

A general and efficient method for the synthesis of tricyclic spirocarbocycles is described. Various cyclic enal-enones were reacted with an N-heterocyclic carbene, and an intramolecular Stetter reaction proceeded smoothly to give various tricyclic spiro-

Palladium-catalyzed asymmetric intermolecular cyclization

Hu, Jian,Hirao, Hajime,Li, Yongxin,Zhou, Jianrong

supporting information, p. 8676 - 8680 (2013/09/12)

Domino cyclization: Alkylpalladium intermediates in an asymmetric Heck reaction were intercepted by a second alkene to give tricyclic products with high enantioselectivity (see scheme; Boc=tert-butoxycarbonyl). The method was applied to the asymmetric syn
