Check Digit Verification of cas no

The CAS Registry Mumber 1098124-33-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,8,1,2 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1098124-33:
(9*1)+(8*0)+(7*9)+(6*8)+(5*1)+(4*2)+(3*4)+(2*3)+(1*3)=154
154 % 10 = 4
So 1098124-33-4 is a valid CAS Registry Number.

Domino heck-aza-Michael reactions: A one-pot, sequential three-component approach to 1,1-dioxido-1,2-benzisothiazoline-3-acetic acid

Rolfe, Alan,Young, Kyle,Hanson, Paul R.

experimental part, p. 5254 - 5262 (2009/06/06)

The development of a new method for the synthesis of 1,1-dioxido-1,2- benzisothiazoline-3-acetic acid by a domino process is reported whereby a classical Heck reaction is coupled to an intramolecular aza-Michael reaction. Ultimately, this method has been expanded to a one-pot, sequential three-component protocol to generate diverse benzofused γ-sultams from a range of commercially available α-bromobenzenesulfonyl chlorides, amines and Michael acceptors.
