Check Digit Verification of cas no

The CAS Registry Mumber 92184-64-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,8 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92184-64:
(7*9)+(6*2)+(5*1)+(4*8)+(3*4)+(2*6)+(1*4)=140
140 % 10 = 0
So 92184-64-0 is a valid CAS Registry Number.

Synthesis and Reactions of Some 1-Substituted 1,2-Diazetidinones

Taylor, Edward C.,Davies, Huw M. L.

, p. 4415 - 4419 (2007/10/02)

A number of 1,2-diazetidin-3-ones variously substituted at N-1 have been prepared by sodium borohydride reduction of, or addition of methylmagnesium bromide to, 3-oxo-1,2-diazetidinium inner salts (formed by condensation of 3-oxo-1,2-diazetidinium tosylate with carbonyl compounds). 1-Cinnamyl-1,2-diazetidin-3-ones, silylated at N-2, underwent base-promoted alkylation and aldol reactions at C-4.Some unusual dimerization and fragmentation reactions of these aza-β-lactam derivatives have been observed.
