Check Digit Verification of cas no

The CAS Registry Mumber 85582-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,8 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85582-50:
(7*8)+(6*5)+(5*5)+(4*8)+(3*2)+(2*5)+(1*0)=159
159 % 10 = 9
So 85582-50-9 is a valid CAS Registry Number.

Syntheses de β-sultames (thiazetidines-1,2 dioxyde-1,1)

Champseix, A.,Chanet, J.,Etienne, A.,Berre, A. Lemasson, J. C.,Napierala, C.,Vessiere, R.

, p. 463 - 472 (2007/10/02)

β-sultams (1,2-thiazetidine-1,1-dioxides) are easily prepared by 1-halogensulphonyl-2-aminoalkane cyclisation. Two processes based upon this principle have permitted the preparation of many variously N and C-substituted β-sultams. 1) In the first method 1-chlorosulphonyl-2-aminoalkane hydrochlorides, prepared from taurines or β-aminothiols, cyclised in the presence of base. 2) The second process involves the spontaneous cyclisation of 1-fluorosulphonyl-2-aminoalkanes prepared Michael addition of primary amines to 1-fluorosulphonylethene.
