Check Digit Verification of cas no

The CAS Registry Mumber 112213-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,2,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112213-42:
(8*1)+(7*1)+(6*2)+(5*2)+(4*1)+(3*3)+(2*4)+(1*2)=60
60 % 10 = 0
So 112213-42-0 is a valid CAS Registry Number.

Catalytic Enantioselective Allylations of Acetylenic Aldehydes via 2-Propanol-Mediated Reductive Coupling

Brito, Gilmar A.,Della-Felice, Franco,Luo, Guoshun,Burns, Alexander S.,Pilli, Ronaldo A.,Rychnovsky, Scott D.,Krische, Michael J.

, p. 4144 - 4147 (2018)

Cyclometalated π-allyliridium C,O-benzoates modified by (S)-SEGPHOS or (S)-Cl,OMe-BIPHEP catalyze enantioselective 2-propanol-mediated reductive couplings of diverse nonmetallic allyl pronucleophiles with the acetylenic aldehyde TIPSC≡CCHO. Absolute stere

Second-generation synthesis of azadirachtin: A concise preparation of the propargylic mesylate fragment

Boyer, Alistair,Veitch, Gemma E.,Beckmann, Edith,Ley, Steven V.

supporting information; experimental part, p. 1317 - 1320 (2009/06/30)

A second bite of the apple: A new and highly efficient synthesis of the propargylic mesylate fragment of azadirachtin has been accomplished (see scheme; Bn=benzyl, Ms=methanesulfonyl, PMB=paramethoxybenzyl, TBDPS=tert- butyldiphenylsilyl). An enantioselec

A divergent synthesis of triyne natural products and glycosylated analogues using a carbenoid rearrangement

Luu, Thanh,Shi, Wei,Lowary, Todd L.,Tykwinski, Rik R.

, p. 3167 - 3178 (2007/10/03)

Using a carbenoid rearrangement to introduce the conjugated acetylenic framework, a series of triynols has been synthesized in five steps from 1,4-butynediol. Several of the triyne alcohols are known natural products and others are glycosylated analogues.

4-(Trialkylsilyl)oxybut-2-ynals as dienophiles in the Diels-Alder synthesis of α-(hydroxymethyl)benzaldehydes

Morrison, Christopher F,Burnell

, p. 7367 - 7369 (2007/10/03)

The α-(hydroxymethyl)benzaldehyde derivative 2 has been synthesized by heating ynal 3 with diene 5, which produced the α-(silyloxymethyl)benzaldehyde 6 by a Diels-Alder/retro-Diels-Alder process, followed by methylation, thioacetalization, and removal of the silyl protecting group. Decarbonylation of α-(silyloxymethyl)benzaldehydes 6 and 10 takes place readily in the presence of zinc(II) chloride or para-toluenesulfonic acid.

Branch, Clive L.,Pearson, Michael J

, p. 1077 - 1096 (2007/10/02)

4-Vinylazetidin-2-one (24) has been converted into 1--4-vinylazetidin-2-one (27) and 1--4-(2-methoxycarbonylvinyl)-azetidin-2-one (43) which on thermolysis in toluene gave (2RS,5RS)-ben
