Check Digit Verification of cas no

The CAS Registry Mumber 108803-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,0 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108803-70:
(8*1)+(7*0)+(6*8)+(5*8)+(4*0)+(3*3)+(2*7)+(1*0)=119
119 % 10 = 9
So 108803-70-9 is a valid CAS Registry Number.

Alkyne Insertion Reactions of Metal-Carbenes Derived from Enynyl α-Diazo Ketones C(CH2)n-2CH=CH2>

Hoye, Thomas R.,Dinsmore, Christopher J.,Johnson, Douglas S.,Korkowski, Paul F.

, p. 4518 - 4520 (2007/10/02)

The title substrates react with a variety of metal catalysts to give metal-dependent product arrays (including tricyclic cyclopropanes and others formally arising from the vinylogous α-keto carbene 3 shown in scheme I) of both synthetic and mechanistic in

Characteristic odoriferous compounds of brown algae: Syntheses of possible oxidation products of (6Z,9Z,12Z,15Z)-1,6,9,12,15-heneicosapentaene and (6Z,9Z,12Z,15Z,18Z)-1,6,9,12,15,18-heneicosahexaene

Broekhof, Nico L.J.M.,Witteveen, Jan G.,Weerdt, Anton J. A. van der

, p. 436 - 442 (2007/10/02)

The unsaturated aldehydes (3Z,6Z)-3,6,11-dodecatrienal (9), (2E,4Z,7Z)-2,4,7,12-tridecatetraenal (10) and (3Z,6Z,9Z)-3,6,9,14-pentadecatetraenal (11) are expected to be products of the air oxidation of heneicosapentaene 1 and heneicosahexaene 2.The first attempts to synthesize aldehydes 9 and 11 (which failed) were based upon repeated Horner-Wittig reactions with phosphine oxide 12.In a second attempt, acetylene chemistry was applied to prepare aldehydes 9, 10 and 11.Their olfactive properties are described.
