Check Digit Verification of cas no

The CAS Registry Mumber 71919-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71919-91:
(7*7)+(6*1)+(5*9)+(4*1)+(3*9)+(2*9)+(1*1)=150
150 % 10 = 0
So 71919-91-0 is a valid CAS Registry Number.

Copper-catalyzed radical ring-opening halogenation with HX

Bai, Ming,Duan, Xin-Hua,Guo, Li-Na,Liu, Shuai,Sun, Qing-Xin,Xu, Peng-Fei

supporting information, p. 8652 - 8655 (2021/09/04)

An efficient copper-catalyzed radical ring-opening halogenation with HX (aq) is described. This protocol features redox-neutral conditions, green halogen sources, and a broad substrate scope, providing practical access to distally chlorinated, brominated and iodinated alkyl ketones and alkyl nitriles with moderate to good yields. This journal is

Ring-opening iodination and bromination of unstrained cycloalkanols through ?-scission of alkoxy radicals

Shi, Jiang-Ling,Wang, Yuankai,Wang, Zixuan,Dou, Bowen,Wang, Jianbo

supporting information, p. 5002 - 5005 (2020/05/18)

Ring-opening iodination or bromination of unstrained cycloalkanols with NaI or NaBr and PhI(OAc)2 under visible light irradiation is developed. In this protocol the concentration of I2is modulated through the generation of triiodide (I3-), thus significantly avoiding undesired side reactions. The reaction is under mild conditions and has a wide substrate scope, thus providing a practically useful method for accessing ω-iodo or ω-bromoketones.

Catalytic asymmetric intramolecular homologation of ketones with α-diazoesters: Synthesis of cyclic α-Aryl/Alkyl β-ketoesters

Li, Wei,Tan, Fei,Hao, Xiaoyu,Wang, Gang,Tang, Yu,Liu, Xiaohua,Lin, Lili,Feng, Xiaoming

supporting information, p. 1608 - 1611 (2015/01/30)

A catalytic asymmetric intramolecular homologation of simple ketones with α-diazoesters was firstly accomplished with a chiral N,N′-dioxide-Sc(OTf)3 complex. This method provides an efficient access to chiral cyclic α-aryl/alkyl β-ketoesters containing an all-carbon quaternary stereocenter. Under mild conditions, a variety of aryl- and alkyl-substituted ketone groups reacted with α-diazoester groups smoothly through an intramolecular addition/rearrangement process, producing the β-ketoesters in high yield and enantiomeric excess.
