Check Digit Verification of cas no

The CAS Registry Mumber 195134-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,1,3 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 195134-74:
(8*1)+(7*9)+(6*5)+(5*1)+(4*3)+(3*4)+(2*7)+(1*4)=148
148 % 10 = 8
So 195134-74-8 is a valid CAS Registry Number.

Copper-catalyzed direct amination of benzylic hydrocarbons and inactive aliphatic alkanes with arylamines

Jin, Shengzhou,Lin, Sen,Xie, Bo,Yan, Zhaohua,Yao, Hua,Zhong, Xiaoyang

supporting information, p. 3263 - 3268 (2020/05/14)

A new synthetic method toward direct C-N bond formation through saturated C-H amination of benzylic hydrocarbons and inactive aliphatic alkanes with primary aromatic amines under an inexpensive catalyst/oxidant (Cu/DTBP) system has been developed. Both aminopyridines and anilines could react smoothly with primary and secondary benzylic C-H substrates or cyclohexane to form the corresponding aromatic secondary amines in moderate to good yields. This protocol has the advantages of wide functional group tolerance and use of readily available raw materials.

Synthesis of the marine dibromooxoindoline convolutamydine C

Miah, Soyfur,Moody, Christopher J.,Richards, Ian C.,Slawin, Alexandra M. Z.

, p. 2405 - 2412 (2007/10/03)

A synthesis of the marine 4,6-dibromo-3-hydroxyoxoindoline convolutamydine C 3 is described. The key steps are the rhodium(II) perfluorobutyramide catalysed cyclisation of diazoamide 17 to give the oxoindoline 18, and the subsequent high yielding one-pot hydrolysis-decarboxylation-oxidation of 19 to 20. X-Ray crystal structures have been determined for the diazoamides 10 and 17 and for the oxoindolines 11 and 13.
