99661-12-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99661-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,6 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99661-12:
(7*9)+(6*9)+(5*6)+(4*6)+(3*1)+(2*1)+(1*2)=178
178 % 10 = 8
So 99661-12-8 is a valid CAS Registry Number.

Directed metalation and regioselective functionalization of 3-bromofuran and related heterocycles with NaHMDS

Zhao, Hang,Dankwardt, John W.,Koenig, Stefan G.,Singh, Surendra P.

supporting information; experimental part, p. 166 - 169 (2012/01/30)

A mild and regioselective functionalization protocol for 3-bromofuran and analogs has been developed. Selective metalation and functionalization of C2 can be achieved as a result of the directing effect of the adjacent electron-withdrawing bromo group. In addition, the C5 position can also be selectively functionalized by blocking the C2 position via silylation or by simply controlling the reaction temperature. These functionalized compounds bearing a C3 bromo substituent may be further elaborated by utilizing a Suzuki-Miyaura cross-coupling procedure.
