147688-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147688-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,6,8 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 147688-25:
(8*1)+(7*4)+(6*7)+(5*6)+(4*8)+(3*8)+(2*2)+(1*5)=173
173 % 10 = 3
So 147688-25-3 is a valid CAS Registry Number.

Studies on development of sufficiently chemoselective N-acylation reagents: N-Acyl-N-(2,3,4,5,6-pentafluorophenyl)methanesulfonamides

Kondo, Kazuhiro,Sekimoto, Erika,Nakao, Junko,Murakami, Yasuoki

, p. 5843 - 5856 (2007/10/03)

A variety of storable N-acyl-N-(2,3,4,5,6-pentafluorophenyl)methanesulfonamides (4a-e) prepared from N-2,3,4,5,6-pentafluorophenylmethanesulfonamide (3), have been developed after systematic research on the structure-reactivity relationship and were found to serve as N-acylation reagents exhibiting sufficiently good chemoselectivity.

N-Benzyloxycarbonylaziridine in the Syntheses of 2-Aminoethyl Armed Lariats and Selectively N-Protected Polyazacrown Ethers

Zinic, Mladen,Alihodzic, Sulejman,Skaric, Vinko

, p. 21 - 26 (2007/10/02)

The 15- and 18-membered mono- and bi-bracchial N-aminoethylene armed lariats 6, 7 and 8 have been synthesized by alkylations of parent azacrowns using N-benzyloxycarbonylaziridine 2 and subsequent removal of Z-protecting groups by catalytic hydrogenolysis
