Check Digit Verification of cas no

The CAS Registry Mumber 32353-96-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,5 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32353-96:
(7*3)+(6*2)+(5*3)+(4*5)+(3*3)+(2*9)+(1*6)=101
101 % 10 = 1
So 32353-96-1 is a valid CAS Registry Number.

A practical synthesis of functionalized isoindolinones via [3?+?3] benzannulation of 1,3-bissulfonylpropenes and 4-arylmethylene-2,3-dioxopyrrolidines

Tang, Xiang-zheng,zhou, Jing-xuan,Liang, Hua-ju,Zhang, Xue-jing,Yan, Ming,Chan, Albert S.C.

, p. 147 - 149 (2018/12/11)

A straightforward synthesis of isoindolinones has been developed via a [3 + 3] benzannulation of 4-arylmethylene-2,3-dioxopyrrolidines and 1,3-bissulfonylpropenes (or 4-sulfonylcrotonates). A series of functionalized isoindolinones were obtained in excellent yields. The reaction could be carried out under mild conditions without transition metal catalyst. The finding provides a practical approach for the preparation of isoindolinone derivatives with potential biological activities.

Direct N-H/α,α,β,β-C(sp3)-H functionalization of piperidine via an azomethine ylide route: synthesis of spirooxindoles bearing 3-substituted oxindoles

Du, Yanlong,Yu, Aimin,Jia, Jiru,Zhang, Youquan,Meng, Xiangtai

, p. 1684 - 1687 (2017/02/10)

A protocol for the direct functionalization of N-H/α,α,β,β-C(sp3)-H of piperidine without any metal or external oxidants is reported. This reaction is promoted by 4-(trifluoromethyl)benzoic acid via an azomethine ylide intermediate. This is a simple method for the synthesis of spirooxindoles bearing 3-substituted oxindole moieties.

A SIMPLE METHOD FOR THE SYNTHESIS OF γ-FUNCTIONALIZED VINYL AND ALLYL SULFONES

Najera, Carmen,Perez-Pinar, Alfonso,Sansano, Jose M.

, p. 6337 - 6352 (2007/10/02)

The synthesis of γ-functionalized vinyl sulfones 3 have been carried out directly starting from dibromides 2 derived from allyl sulfones 1 by reaction with different nucleophiles.The process is stereoselective affording compounds 3 with E configuration ex
