404392-85-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404392-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,3,9 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 404392-85:
(8*4)+(7*0)+(6*4)+(5*3)+(4*9)+(3*2)+(2*8)+(1*5)=134
134 % 10 = 4
So 404392-85-4 is a valid CAS Registry Number.

Si-BEZA - Catalytic pyridinium triflate: A mild and powerful agent for the silylation of alcohols

Misaki,Kurihara,Tanabe

, p. 2478 - 2479 (2007/10/03)

A highly efficient method of silylation using a novel agent, Si-BEZA (silylbenzamide), together with a pyridinium triflate catalyst was developed, wherein a variety of silyl groups can be introduced into sterically crowded alcohols under mild conditions.

Comparative Study of the Diastereoselective Addition of Allenyl Zinc Reagents to α-Alkoxy (or Silyloxy) Aldehydes and Imines. A Straightforward Synthesis of Amino Alcohols from Imines

Poisson, Jean-Francois,Normant, Jean F.

, p. 6553 - 6560 (2007/10/03)

The addition of allenylzinc bromides to α-chiral imines proceeds with very high diastereoselectivity. This result is in contrast with the addition to the corresponding aldehydes, leading to poor diastereoselectivity. The anti/anti adducts are explained by Felkin-Ahn and Gaudemar-Yamamoto models of the transition state.
