Check Digit Verification of cas no

The CAS Registry Mumber 1341189-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,1,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1341189-52:
(9*1)+(8*3)+(7*4)+(6*1)+(5*1)+(4*8)+(3*9)+(2*5)+(1*2)=143
143 % 10 = 3
So 1341189-52-3 is a valid CAS Registry Number.

Nonconcerted cycloaddition of 2H-azirines to acylketenes: A route to N-bridgehead heterocycles

Khlebnikov, Alexander F.,Novikov, Mikhail S.,Pakalnis, Viktoriia V.,Yufit, Dmitry S.

experimental part, p. 9344 - 9352 (2012/01/05)

Reactions of acylketenes, generated from diazo diketones, with 2-unsubstituted and 2-monosubstituted 3-aryl-2H-azirines lead to 1:1 or 2:1 adducts, which are derivatives of 5-oxa-1-azabicyclo[4.1.0]hept-3-ene or 5,7-dioxa-1-azabicyclo[4.4.1]undeca-3,8-diene. According to DFT B3LYP/6-31G(d) computations, the formation of (4+2)-monoadducts proceeds via a stepwise non-pericyclic mechanism. Reaction with methanol transforms quantitatively both 1:1 and 2:1 adducts into 1,4-oxazepine derivatives.
