Check Digit Verification of cas no

The CAS Registry Mumber 488151-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,8,1,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 488151-80:
(8*4)+(7*8)+(6*8)+(5*1)+(4*5)+(3*1)+(2*8)+(1*0)=180
180 % 10 = 0
So 488151-80-0 is a valid CAS Registry Number.

Intramolecular Sakurai Allylation of Geminal Bis(silyl) Enamide with Indolenine. A Diastereoselective Cyclization to Form Functionalized Hexahydropyrido[3,4- b]Indole

Chen, Yi,Gao, Lu,Song, Xuanyi,Song, Zhenlei

, p. 124 - 128 (2021/01/13)

A fluoride-promoted intramolecular Sakurai allylation of geminal bis(silyl) enamide with indolenine has been developed. The reaction facilitates an efficient cyclization to give hexahydropyrido[3,4-b]indoles in good yields with high diastereoselectivity. The resulted cis, trans-stereochemistry further enables the ring-closing metathesis (RCM) reaction of two alkene moieties, giving a tetracyclic N-hetereocycle widely found as the core structure in akuammiline alkaloids.

Iridium-Catalyzed Propenylation Reactions for the Synthesis of 4-Pyridone Derivatives

Bai, Xue-dan,Wang, Jie,He, Ying

supporting information, p. 496 - 501 (2019/01/04)

Herein we report an iridium-catalyzed propenylation reaction of allylic carbonates with 4-hydroxypyridine derivatives. The process efficiently provides 4-pyridone derivatives with high stereoselectivities under mild conditions. The products could constitute valuable building blocks for the synthesis of natural products and other bioactive molecules. Preliminary mechanistic studies indicated that a tandem allylic substitution/isomerization reaction occurs to afford the propenylation products. (Figure presented.).

Electrochemical carboxylation of benzylic carbonates: Alternative method for efficient synthesis of arylacetic acids

Ohkoshi, Masashi,Michinishi, Jun-Ya,Hara, Shoji,Senboku, Hisanori

experimental part, p. 7732 - 7737 (2010/10/21)

Electrochemical carboxylation of benzylic carbonates was successfully performed as an alternative method for the synthesis of phenylacetic acids by using a one-compartment cell equipped with a Pt plate cathode and an Mg rod anode in CH3CN to afford the corresponding phenylacetic acids in good yields.
