Check Digit Verification of cas no

The CAS Registry Mumber 1023964-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,6 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1023964-69:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*6)+(3*4)+(2*6)+(1*9)=143
143 % 10 = 3
So 1023964-69-3 is a valid CAS Registry Number.

Benzothiazines in synthesis: A route to chiral cyclobutanes

Harmata, Michael,Ying, Weijiang,Hong, Xuechuan,Barnes, Charles L.

, p. 594 - 604 (2008/12/21)

Using enantiomerically pure benzothiazines as templates, enantiomerically pure cyclobutanes were prepared. Such compounds are potentially interesting synthetic intermediates. The sequence developed for the preparation of these compounds, as well as some of their chemistry, is described. Georg Thieme Verlag Stuttgart.
