3755-85-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3755-85-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,5 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3755-85:
(6*3)+(5*7)+(4*5)+(3*5)+(2*8)+(1*5)=109
109 % 10 = 9
So 3755-85-9 is a valid CAS Registry Number.

A Convenient Synthesis of Aminomethyl Ketones (α-Amino Ketones)

Yinglin, Han,Hongwen, Hu

, p. 615 - 618 (2007/10/02)

Several N,N-diformylaminomethyl ketones 3 were prepared by treating the respective bromomethylketone 1 with sodium diformylamide in acetonitrile at room temperature.This reaction produced from N-formylaminomethyl ketones 4 when ethanol was used as the solvent.One of the formyl groups of N,N-difomylaminomethyl ketones was selectively removed by using a catalytic amount of sodium or potassium hydroxide in alcohol to the corresponding N-formylaminomethyl ketones 4.The formyl groups of both N,N-diformyl- and N-formylaminomethyl ketones could be easily removed by either5percent hydrochloric acid in ethanol or 6N hydrochloric acid to give the corresponding aminomethyl ketone hydrochlorides 5.These reactions are general and give high yield of the products.
