Check Digit Verification of cas no

The CAS Registry Mumber 28691-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,9 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28691-78:
(7*2)+(6*8)+(5*6)+(4*9)+(3*1)+(2*7)+(1*8)=153
153 % 10 = 3
So 28691-78-3 is a valid CAS Registry Number.

Solvent- and catalyst-free regioselective hydrophosphanation of alkenes

Alonso, Francisco,Moglie, Yanina,Radivoy, Gabriel,Yus, Miguel

supporting information, p. 2699 - 2702 (2012/11/07)

The hydrophosphanation of alkenes, an atom-economy process typically promoted by radicals or metal species, has been shown to take place in the absence of a catalyst, under solvent-free conditions and in a regioselective manner.

Synthesis of 5-aminoisoxazolines from N-allyl compounds and nitrile oxides via tandem isomerization-1,3-dipolar cycloaddition

Bujak, Piotr,Krompiec, Stanis?aw,Malarz, Joanna,Krompiec, Micha?,Filapek, Micha?,Danikiewicz, Witold,Kania, Magdalena,Gbarowska, Katarzyna,Grudzka, Iwona

experimental part, p. 5972 - 5981 (2010/09/18)

A new strategy for the synthesis of derivatives of 5-aminoisoxazolines via tandem catalytic isomerization (of N-allyl systems to N-(1-propenyl) systems) - 1,3-dipolar cycloaddition (of a stable nitrile oxide to N-(1-propenyl) systems) is presented. Rhodiu
