Check Digit Verification of cas no

The CAS Registry Mumber 13667-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,6 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13667-78:
(7*1)+(6*3)+(5*6)+(4*6)+(3*7)+(2*7)+(1*8)=122
122 % 10 = 2
So 13667-78-2 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

Synthesis and domino reactions of 1,1-bis(hydroxymethyl)allenes

Langer, Peter

, p. 1217 - 1218 (2007/10/03)

The reaction of dilithiated 1,1-diphenylallene with aryl ketones provides a convenient access to novel 1,1-bis(hydroxymethyl)allenes, which undergo Friedel-Crafts-type domino reactions upon treatment with TsOH.
