100101-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100101-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,1,0 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100101-45:
(8*1)+(7*0)+(6*0)+(5*1)+(4*0)+(3*1)+(2*4)+(1*5)=29
29 % 10 = 9
So 100101-45-9 is a valid CAS Registry Number.

Synthesis of chiral 4-substituted 2-hydroxypent-4-enoic acid derivatives via diastereoselective ene reaction promoted by ZnBr2

Kwiatkowski, Piotr,Kwiatkowski, Jacek,Majer, Jakub,Jurczak, Janusz

, p. 215 - 223 (2007/10/03)

The diastereoselective carbonyl-ene reaction of various 1,1-disubstituted olefins with the chiral derivatives of glyoxylic acid, with Oppolzer's sultam 1a and 8-phenylmenthol 1b auxiliaries, was studied. The reaction proceeds effectively under undemanding

ASYMMETRIC INDUCTION IN THE ENE REACTION OF GLYOXYLATE ESTERS OF 8-PHENYLMENTHOL

Whitesell, James K.,Bhattacharya, Apurba,Buchanan, Charles M.,Chen, H. H.,Deyo, Don,et al.

, p. 2993 - 3002 (2007/10/02)

We recently communicated (J.K.Whitesell, A.Bhattacharya, D.A.Aguilar and K.Henke, J.Chem.Soc.Chem.Commun. 989 (1982)) a highly efficient and effective method for the control of absolute stereochemistry through asymmetric induction in the ene reaction the chiral glyoxylate 1 with alkenes.We now have accumulated sufficient information on this process in terms of both its mechanistic details as well as its scope and applicability to a variety of situations that warrants a more complete presentation of these reactions.
