24907-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24907-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,9,0 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24907-33:
(7*2)+(6*4)+(5*9)+(4*0)+(3*7)+(2*3)+(1*3)=113
113 % 10 = 3
So 24907-33-3 is a valid CAS Registry Number.

Formation of α-Monosubstituted propargylamines from terminal alkynes and secondary amines using a (PNO)Rh/Cu Tandem catalyst system

Takano, Shotaro,Kochi, Takuya,Kakiuchi, Fumitoshi

supporting information, p. 1620 - 1623 (2017/11/04)

A novel (PNO)Rh/CuBr (PNO: phosphine-quinolinolate) tandem catalyst system was developed for facile synthesis of α-monosubstituted propargylamines from aliphatic terminal al-kynes and secondary amines. Various terminal alkynes and amines were applicable t

Zn(OAc)2·2H2O: a versatile catalyst for the one-pot synthesis of propargylamines

Ramu, Enugala,Varala, Ravi,Sreelatha, Nuvula,Adapa, Srinivas R.

, p. 7184 - 7190 (2008/03/11)

An inexpensive and readily available catalyst, Zn(OAc)2·2H2O is successfully evaluated for effective one-pot synthesis of propargylamines with moderate to excellent yields for most of the substrates screened, without the need of base, co-catalyst or additive in the presence of air.
