Check Digit Verification of cas no

The CAS Registry Mumber 100298-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,9 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 100298-25:
(8*1)+(7*0)+(6*0)+(5*2)+(4*9)+(3*8)+(2*2)+(1*5)=87
87 % 10 = 7

Synthesis and R eactions of Some 2,2-Disubstitued 1,2-Diazetidin-3-ones: An Intramolecular Aldol Approach to Bicyclic Systems

Taylor, Edward C.,Davies, Huw M. L.,Hinkle, Jeffery S.

, p. 1530 - 1536 (2007/10/02)

Several procedures have been developed for alkylation at N-2 of a variety of 1,2-diazetidin-3-ones with N-1 substituent carrying an olefinic bond.Ozonolysis yielded aldehydes which were subjected to aldol cyclization conditions.The products proved to be rearranged bicyclic products arising from intramolecular ring opening of the 1,2-diazetidin-3-one lactam bond by the secondary hydroxyl group formed in the aldol reaction.
