Check Digit Verification of cas no

The CAS Registry Mumber 24281-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,8 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24281-07:
(7*2)+(6*4)+(5*2)+(4*8)+(3*1)+(2*0)+(1*7)=90
90 % 10 = 0
So 24281-07-0 is a valid CAS Registry Number.

Lewis basic selenium catalyzed chloroamidation of olefins using nitriles as the nucleophiles

Tay, Daniel Weiliang,Tsoi, Ivan Tan,Er, Jun Cheng,Leung, Gulice Yiu Chung,Yeung, Ying-Yeung

supporting information, p. 1310 - 1313 (2013/04/24)

A Lewis base catalyzed chloroamidation of olefinic substrates was achieved using diphenyl selenide as the catalyst. The reaction conditions are mild and suitable for a wide range of substrates including those which are acid labile.

New method for chloroamidation of olefins. Application in the synthesis of N-glycopeptides and anticancer agents

Rawal, Girish K.,Kumar, Amit,Tawar, Urmila,Vankar, Yashwant D.

, p. 5171 - 5174 (2008/09/17)

(Chemical Equation Presented) Chloroamidation of olefins using a new reagent system (COCl)2-AgNO3-CH3CN was observed. Various glycals with this reagent system produce 2-chloro-1-acetamido sugars in good yields which, in turn, were converted to free amino derivatives and various glycopeptides. The acetamido sugar derivatives and free amines were found to be promising anticancer agents against the U-87 malignant glyoma (a brain tumor) cell line with IC-50 = 1 nm-22 μM, and they were found to be far less cytotoxic against a normal human embryonic kidney cell line.

Addition reactions of nitryl chloride at multiple bonds

Zyk,Bondarenko,Nesterov,Zefirov

, p. 980 - 986 (2007/10/03)

Published data on additio of nitryl chloride to alkenes and possible reaction mechanisms were analyzed. Reactions of nitryl chloride with alkenes differing in the ionization potentials of the double bond and in the abilities to undergo various structural rearrangements were studied. Nitryl chloride was shown to be very sensitive both to the substrate and to the reaction conditions.
