Check Digit Verification of cas no

The CAS Registry Mumber 1489-22-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1489-22:
(6*1)+(5*4)+(4*8)+(3*9)+(2*2)+(1*2)=91
91 % 10 = 1
So 1489-22-1 is a valid CAS Registry Number.

New method for the preparation of dibenzo[b,f][1,4]thiazepines

Fujii, Takayoshi,Hao, Wei,Yoshimura, Toshiaki

, p. 246 - 250 (2004)

The S-amination of 9H-thioxanthen-9-ol (2a) and 9-substituted derivatives 2b-e (Me (b), Et (c), iPr (d), Ph (e)) with O- mesitylenesulfonylhydroxylamine (MSH) was carried out. The expected product, 10-amino-9-hydroxy-9-isopropyl-9H-thioxanthenium mesitylenesulfonate (3d), was obtained in 78% yield from the corresponding thioxanthen-9-ol 2d. However, in the case of 2a-c and 2e the reaction led instead to dibenzo[b, f][1,4]thiazepines 6a-c and 6e in moderate yields.
