Check Digit Verification of cas no

The CAS Registry Mumber 226387-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,3,8 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 226387-80:
(8*2)+(7*2)+(6*6)+(5*3)+(4*8)+(3*7)+(2*8)+(1*0)=150
150 % 10 = 0
So 226387-80-0 is a valid CAS Registry Number.

A facile lipase-catalyzed KR approach toward enantiomerically enriched homopropargyl alcohols

Borowiecki, Pawe?,Dranka, Maciej

, (2019)

Compounds possessing propargylic (prop-2-ynylic) system are very important building blocks for organic chemistry. Among them, preparation of enantiomeric homopropargyl alcohols (but-3-yn-1-ols) constitutes a key-challenge for asymmetric synthesis and thus

A bicyclization reaction with two molecular allenyl ketones and isocyanides: Synthesis of a lactone-containing azaspirocycle derivative

supporting information, p. 7231 - 7234 (2019/07/02)

A novel bicyclization reaction of two molecular allenyl ketones and isocyanides has been disclosed. This strategy allows for the construction of structurally complex spirocyclic lactam-lactone systems in an efficient manner. This protocol also demonstrate

Efficient synthesis of 3-chloromethyl-2(5H)-furanones and 3-chloromethyl- 5,6-dihydropyran-2-ones via the PdCl2-catalyzed chlorocyclocarbonylation of 2,3- or 3,4-allenols

Cheng, Xin,Jiang, Xuefeng,Yu, Yihua,Ma, Shengming

scheme or table, p. 8960 - 8965 (2009/04/11)

(Chemical Equation Presented) A mild and efficient methodology involving PdCl2-catalyzed chlorocyclocarbonylation of 2,3- or 3,4-allenols with CuCl2 for the synthesis of 3-chloromethyl-2(5H)-furanones and 3-chloromethyl-5,6-dihydropyran-2-ones was developed. This reaction proceeded in a highly regioselective manner, i.e., the chlorine atom was introduced to the terminal position of the allene moiety while the lactone linkage was formed between the center carbon atom of the allene moiety and the hydroxyl oxygen, which was established by the X-ray single crystal diffraction study of γ-lactone 3p. The highly optically active 3-chloromethyl-2(5H)-furanones could be easily prepared from the readily available optically active 2,3-allenols. A mechanism for this reaction was proposed.
