Check Digit Verification of cas no
The CAS Registry Mumber 169696-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,9 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 169696-27:
(8*1)+(7*6)+(6*9)+(5*6)+(4*9)+(3*6)+(2*2)+(1*7)=199
199 % 10 = 9
So 169696-27-9 is a valid CAS Registry Number.

Direct transformation of silyl enol ethers into functionalized allenes
Langer, Peter,Doering, Manfred,Seyferth, Dietmar,Goerls, Helmar
, p. 573 - 584 (2007/10/03)
The first elimination reactions of silyl enol ethers to lithiated allenes are reported. These reactions allow a direct transformation of readily available silyl enol ethers into functionalized allenes. The action of three to four equivalents of lithium di
