18156-91-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18156-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,5 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18156-91:
(7*1)+(6*8)+(5*1)+(4*5)+(3*6)+(2*9)+(1*1)=117
117 % 10 = 7
So 18156-91-7 is a valid CAS Registry Number.

1,6-Dihydro-1,6-disilapentalene derivatives by 1,1-organoboration of triynes

Wrackmeyer, Bernd,Kehr, Gerald,Suess, Juergen,Molla, Elias

, p. 207 - 215 (2007/10/03)

The triynes R1CC-SiMe2-CC-SiMe2-CCR 1 [R1=H (3), SiMe3 (4) SnMe3 (5)] were prepared, and their reactivity towards triorganoboranes R3B 6 [R=Et (a), CH2Ph (b), Ph (c), 2-thienyl (d)] was studied. In the case of 3, decomposition was observed whereas the reaction of 4 and 5 with 6 affords the 1,6-dihydro-1,6-disilapentalene derivatives 7a-d (from 4) and 9a, c (from 5) in almost quantitative yield. This is the result of stereo- and regioselective intermolecular 1,1-organoboration in the first step of the reaction, followed by two consecutive intramolecular 1,1-vinyloborations. The products were characterised by their 1H-, 11B-, 13C-, 29Si- and 119Sn-NMR data.
