Check Digit Verification of cas no

The CAS Registry Mumber 1338951-16-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,9,5 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1338951-16:
(9*1)+(8*3)+(7*3)+(6*8)+(5*9)+(4*5)+(3*1)+(2*1)+(1*6)=178
178 % 10 = 8
So 1338951-16-8 is a valid CAS Registry Number.

Synthesis of novel β-aminocyclobutanecarboxylic acid derivatives by a solvent-free aza-Michael addition and subsequent ring closure

Meiresonne, Tamara,Mangelinckx, Sven,De Kimpe, Norbert

, p. 7085 - 7091 (2011/11/04)

Novel β-aminocyclobutanecarboxylic acid derivatives were prepared via a sequential solvent-free aza-Michael addition of benzophenone imine across 3-halopropylidenemalonates and base-induced ring closure. These highly substituted cyclobutanedicarboxylic acid derivatives were subjected to a reactivity study which demonstrated the tendency of these donor-acceptor substituted four-membered rings to be converted into their corresponding ring-opened products.
