1237789-94-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1237789-94-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,8 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1237789-94:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*8)+(3*9)+(2*9)+(1*4)=204
204 % 10 = 4
So 1237789-94-4 is a valid CAS Registry Number.

Efficient iron-catalyzed Tsuji-trost coupling reaction of aromatic allylic amides through a sp3-carbon-nitrogen breaking

supporting information; experimental part, p. 1251 - 1254 (2010/08/05)

The catalytic activation of sp3-carbon-nitrogen of allylic amides is generally difficult because of the inefficient leaving-group ability of the amide group. In this article, we have discovered for the first time that FeCl3-catalyzed Tsuji-Trost coupling reaction of aromatic allylic amides with active methylene compounds, cyclohexanone, and allytrimethylsilane work efficiently under mild conditions.
