Check Digit Verification of cas no

The CAS Registry Mumber 33143-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,1,4 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33143-51:
(7*3)+(6*3)+(5*1)+(4*4)+(3*3)+(2*5)+(1*1)=80
80 % 10 = 0
So 33143-51-0 is a valid CAS Registry Number.

Rapid and convenient microwave-assisted synthesis of primary amines via reductive N-alkylation of methyl carbamate with aldehydes

Lehmann, Fredrik,Scobie, Martin

, p. 1679 - 1681 (2008)

Microwave-assisted reductive alkylation of methyl carbamate with a range of aldehydes provides, after basic work-up, an experimentally simple, one-pot method for rapid functional group interconversion of structurally diverse aldehydes into primary amines. The method has several advantages over more traditional methods of carrying out this transformation and is particularly amenable to high-throughput synthesis.

Synthesis of N-protected allylic amines from allyl ethers

Kim, Ji Duck,Lee, Min Hee,Han, Gyoonhee,Park, Hyunju,Zee, Ok Pyo,Jung, Young Hoon

, p. 8257 - 8266 (2007/10/03)

A synthetic method for N-protected allylic amines from allyl ethers using chlorosulfonyl isocyanate (CSI) is presented. The reaction of 4-phenylbut-2-enyl methyl ether (1i) with CSI afforded methyl N-(1-benzylallyl)carbamate (2i) and methyl N-(4-phenylbut

Palladium(0)-Catalyzed Amination of Allylic Acetate with Methyl Carbamate

Takagi, Masatoshi,Yamamoto, Keiji

, p. 2123 - 2124 (2007/10/02)

Methyl sodiocarbamate, a recalcitrant nucleophile toward ?-allylpalladium intermediate, was found to react with allylic acetates to give allylic carbamates in the presence of a catalytic amount of Pd(PPh3)4 in THF-DMSO mixed solvent.
