164334-44-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 164334-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,3,3 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 164334-44:
(8*1)+(7*6)+(6*4)+(5*3)+(4*3)+(3*4)+(2*4)+(1*4)=125
125 % 10 = 5
So 164334-44-5 is a valid CAS Registry Number.

Highly Stereocontrolled Sequential Asymmetric Michael Addition Reactions with Cinnamate Esters - Generation of Three and Four Contiguous Stereogenic Centers on Seven-Carbon Acyclic Motifs

Hanessian, Stephen,Gomtsiyan, Arthur

, p. 7509 - 7512 (1994)

The reaction of allyl and crotyl bicyclic chiral phosphonamide anions with two cinnamate esters leads to a sequential Michael reaction with excellent diastereoselectivity.The option to quench enolates with methyl iodide greatly enhances the versatility of
