391612-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 391612-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,6,1 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 391612-42:
(8*3)+(7*9)+(6*1)+(5*6)+(4*1)+(3*2)+(2*4)+(1*2)=143
143 % 10 = 3
So 391612-42-3 is a valid CAS Registry Number.

Highly asymmetric bromocyclization of tryptophol: Unexpected accelerating effect of DABCO-derived bromine complex

Liu, Huan,Jiang, Guangde,Pan, Xixian,Wan, Xiaolong,Lai, Yisheng,Ma, Dawei,Xie, Weiqing

supporting information, p. 1908 - 1911 (2014/05/06)

Highly asymmetric bromocyclization of tryptophol by using chiral anionic phase-transfer catalyst and DABCO-derived brominating reagent is described. Optimization of the reaction conditions revealed that the reaction rate was accelerated together with impr
