Check Digit Verification of cas no

The CAS Registry Mumber 70982-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,8 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70982-50:
(7*7)+(6*0)+(5*9)+(4*8)+(3*2)+(2*5)+(1*0)=142
142 % 10 = 2
So 70982-50-2 is a valid CAS Registry Number.

Azetidinone Antibiotics. 22. A Rearrangement of Oxoazetidinesulfinic Acids to Haloazetidinones

Spitzer, Wayne A.,Goodson, Theodore,Lammert, Steven R.,Kukolja, Stjepan

, p. 3568 - 3570 (1981)

Treatment of the oxoazetidinesulfinic acid 3 with a positive halogen source gave trans and cis 4-haloazetidinones 5; the trans isomer of 5 are easily converted to oxazoline 6 by chromatography on silica gel, while the cis isomers are transformed into 6 by
