1243539-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1243539-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,5,3 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243539-57:
(9*1)+(8*2)+(7*4)+(6*3)+(5*5)+(4*3)+(3*9)+(2*5)+(1*7)=152
152 % 10 = 2
So 1243539-57-2 is a valid CAS Registry Number.

Enantioconservative synthesis of polysubstituted pyrimido[4,5- b ]azepines

Gerig, Britta,Girreser, Ulrich,Schuett, Martin,Heber, Dieter

experimental part, p. 2017 - 2022 (2010/08/22)

A three-step enantioconservative protocol was developed for the synthesis of polysubstituted pyrimido[4,5-b]azepines. First, 1,3-dimethyl-6-[N-(2- alkoxycarbonylalkyl)amino]uracils were synthesized by nucleophilic substitution of 6-chloro-1,3-dimethyluracil with amino acids. Subsequent acylation of the uracils by a mixture of acetic anhydride and cyanoacetic acid gave the corresponding 5-cyanoacetylated pyrimidines. In the final step, the pyrimidines were subjected to Dieckmann cyclization with a sodium alcoholate in the corresponding alcohol to afford the corresponding pyrimido[4,5-b]azepines. By using uracils of N-monosubstituted amino acids, cyclization was combined with ring opening of the pyrimidine ring system to afford polysubstituted azepines. Georg Thieme Verlag Stuttgart.
