57600-76-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57600-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,0 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57600-76:
(7*5)+(6*7)+(5*6)+(4*0)+(3*0)+(2*7)+(1*6)=127
127 % 10 = 7
So 57600-76-7 is a valid CAS Registry Number.

Facile preparation of aromatic ketones from aromatic bromides and arenes with aldehydes

Ushijima, Sousuke,Dohi, Souya,Moriyama, Katsuhiko,Togo, Hideo

experimental part, p. 1436 - 1442 (2012/03/09)

Aromatic ketones were efficiently prepared in good yields by the reactions of aryl bromides with n-BuLi, followed by the reactions with aromatic aldehydes or aliphatic aldehydes and the subsequent treatment with molecular iodine and K2CO3, in a one-pot method. The same treatment of arenes, instead of aromatic bromides, also provided the corresponding aromatic ketones in good yields. Using these methods, various diaryl ketones and alkyl aryl ketones bearing electron-rich aromatics and electron-deficient aromatics could be prepared efficiently by a simple, transition-metal-free, and therefore environmentally benign experimental procedure.
