749862-73-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 749862-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,8,6 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 749862-73:
(8*7)+(7*4)+(6*9)+(5*8)+(4*6)+(3*2)+(2*7)+(1*3)=225
225 % 10 = 5
So 749862-73-5 is a valid CAS Registry Number.

Formation and utility of azasilacyclopentadienes derived from silacyclopropenes and nitriles

Anderson, Laura L.,Woerpel

supporting information; experimental part, p. 425 - 428 (2009/07/11)

(Chemical Equation Presented) The copper-catalyzed insertions of nitriles into the Si-C bonds of silacyclopropenes provide azasilacyclopentadienes, which can be converted to allylic amines after reduction and protodesilylation. The enamine functionality o

Formation and utility of oxasilacyclopentenes derived from functionalized alkynes

Clark, Timothy B.,Woerpel

, p. 9522 - 9523 (2007/10/03)

Oxasilacyclopentenes were shown to be synthetically useful masked allylic alcohols constructed in high yields and regioselectivities from terminal and internal alkynes. Several functional groups were shown to be tolerated utilizing silver-catalyzed silacy
