Check Digit Verification of cas no

The CAS Registry Mumber 300561-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,5,6 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 300561-17:
(8*3)+(7*0)+(6*0)+(5*5)+(4*6)+(3*1)+(2*1)+(1*7)=85
85 % 10 = 5
So 300561-17-5 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.
