491572-04-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 491572-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,5,7 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 491572-04:
(8*4)+(7*9)+(6*1)+(5*5)+(4*7)+(3*2)+(2*0)+(1*4)=164
164 % 10 = 4
So 491572-04-4 is a valid CAS Registry Number.

An effective synthesis of α-cyanoenamines by Peterson olefination

Adam, Waldemar,Ortega-Schulte, Claudio M.

, p. 414 - 416 (2007/10/03)

A convenient and gentle method for the synthesis of α-cyanoenamines based on the Peterson olefination has been developed. For these sensitive, highly functionalized olefins, the present method is superior to the Horner-Emmons condensation, as manifested by the higher yields and broader scope.

Regioselective preparation of 2-substituted 3,4-diaryl pyrroles: A concise total synthesis of ningalin B

Bullington, James L.,Wolff, Russell R.,Jackson, Paul F.

, p. 9439 - 9442 (2007/10/03)

Methylisocyanoacetate undergoes a 2 + 3 cycloaddition with α,β-unsaturated nitriles to provide a regioselective synthesis of 2-substituted 3,4-diaryl pyrroles. The ease of preparation of α,β-unsaturated nitriles allows the rapid synthesis of pyrroles with varied substituents. Using this method, a key intermediate (1) for the synthesis of the marine natural products lukianol A, lamellarin O, and lamellarin Q was prepared in two steps. A total synthesis of ningalin B (11) was also accomplished utilizing this methodology.
