Check Digit Verification of cas no

The CAS Registry Mumber 1384585-74-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,4,5,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1384585-74:
(9*1)+(8*3)+(7*8)+(6*4)+(5*5)+(4*8)+(3*5)+(2*7)+(1*4)=203
203 % 10 = 3
So 1384585-74-3 is a valid CAS Registry Number.

Use of (Z)-β-(2-fluorobenzenesulfonyl)vinylamines as novel synthons in the synthesis of 1,4-benzothiazine derivatives

Tsui, Gavinchit,Singjunla, Yuttapong,Lautens, Mark

experimental part, p. 1359 - 1364 (2012/06/30)

A novel synthetic route for arylated 1,4-benzothiazine derivatives has been developed. This method utilizes a key intramolecular nucleophilic aromatic substitution step of the corresponding (Z) - (2-fluorobenzenesulfonyl)vinylamine intermediate to construct the benzothiazine ring. A wide range of aryl and heteroaryl substituent groups can be installed from commercial boronic acids. Both mono- and diarylated products have been synthesized in good yields and with good functional group tolerance. Georg Thieme Verlag Stuttgart · New York.
