93011-61-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 93011-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,1 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93011-61:
(7*9)+(6*3)+(5*0)+(4*1)+(3*1)+(2*6)+(1*1)=101
101 % 10 = 1
So 93011-61-1 is a valid CAS Registry Number.

A high-yielding protocol for the synthesis of 4,5-diarylpyrimidin-2-amine derivatives from chalcones

Kooramatom Unni, Krishnaraj,Menon, Prasanth K.,George, Scholly Clair,Thomas, Sajesh P.,Devaky

, p. 112 - 118 (2021/10/07)

A novel, high yielding and versatile protocol was achieved for the synthesis of 4,5-diaryl-2-pyrimidinamine derivatives from chalcones. The synthesis was accomplished by converting the chalcones into 3-chloro-2,3-diaryl-2-propen-1-ones followed by subsequent reaction with amidine derivatives.

Efficient synthesis of deoxybenzoins from chalcones

Mathew, Paulson,Mathew, Daliya,Asokan

, p. 661 - 665 (2007/10/03)

β-Ketoaldehydes derived from chalcone epoxides by Lewis acid-catalyzed rearrangement underwent smooth deformylation when refluxed in tetrahydrofuran (THF) in the presence of ethylenediamine, affording deoxybenzoins in excellent yields. The method is general and useful for the preparation of deoxybenzoins with a variety of substitution patterns. Copyright Taylor & Francis Group, LLC.
