1191924-02-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1191924-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,9,2 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1191924-02:
(9*1)+(8*1)+(7*9)+(6*1)+(5*9)+(4*2)+(3*4)+(2*0)+(1*2)=153
153 % 10 = 3
So 1191924-02-3 is a valid CAS Registry Number.

A versatile preparation of gelaender-type p-terphenyls from a readily available diacetylenic precursor

Modjewski, Matthew,Lindeman, Sergey V.,Rathore, Rajendra

, p. 4656 - 4659 (2009)

A series of doubly bridged p-terphenyls (4) have been synthesized utilizing a facile three-step synthesis starting from the readily available dlacetylenlc precursor (1) In excellent overall yields, and their structures were confirmed by 1H/13 NMR spectroscopy as well as by X-ray crystallography. The racemization barrier between the meso and chlral atropisomers of one of the derivatives of 4 was found to be ~12 kcal/mol by variable-temperature NMR spectroscopy. The versatility of the protocol developed herein was further demonstrated by the preparation of a quadruply bridged penta-p-phenylene derivative.
