Check Digit Verification of cas no

The CAS Registry Mumber 135569-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135569-40:
(8*1)+(7*3)+(6*5)+(5*5)+(4*6)+(3*9)+(2*4)+(1*0)=143
143 % 10 = 3
So 135569-40-3 is a valid CAS Registry Number.

Cycloaddition of (N-Alkyl-N-phenylamino)ketene with Imines

Brady, William T.,Dad, Mohammad M.

, p. 6118 - 6122 (2007/10/02)

(N-Alkyl-N-phenylamino)ketenes were prepared in the presence of various imines, and a cycloaddition reaction occurred to yield 3-(N-alkyl-N-phenylamino)-2-azetidinones.The size and electronic nature of the imine substituents were varied in order to probe those factors that influence the stereochemistry of the cycloaddition.The stereochemistry of the 2-azetidinone was determined by the substitution pattern of the imines.In general, the stereochemistry of the 2-azetidinone products are significantly influenced by the bulk of the N substituent on the imine.These results are discussed in terms of a two-step zwitterionic intermediate.
