Check Digit Verification of cas no

The CAS Registry Mumber 140868-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140868-80:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*8)+(2*8)+(1*0)=140
140 % 10 = 0
So 140868-80-0 is a valid CAS Registry Number.

Selective oxygenation of alkynes: A direct approach to diketones and vinyl acetate

Xia, Xiao-Feng,Gu, Zhen,Liu, Wentao,Wang, Ningning,Wang, Haijun,Xia, Yongmei,Gao, Haiyan,Liu, Xiang

supporting information, p. 9909 - 9913 (2015/01/09)

Arylalkynes can be converted into α-diketones with the use of a copper catalyst, and also be transformed into vinyl acetates under metal-free conditions, both in the presence of PhI(OAc)2 as an oxidant at room temperature. A series of substituted α-diketones were prepared in moderate to good yields. A variety of vinyl halides could be regio- and stereo-selectively synthesized under mild conditions, and I, Br and Cl could be all easily embedded into the alkynes. This journal is

Stereoselective synthesis of 2-functionalized 1-bromo-1-iodo-1-alkenes by electrophilic iodination of 1-bromo-1-alkynes

Barluenga,Rodriguez,Campos

, p. 270 - 272 (2007/10/02)

1-Bromo-1-alkynes 1 react with bis(pyridine)iodine(1) tetrafluoroborate (2) and nucleophiles (AcOH, HCO2H, Cl-, Br-, I-) to give in a stereoselective addition 2-functionalized 1-bromo-1-iodo-1-alkenes 3.
