1428883-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1428883-53-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,8,8 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1428883-53:
(9*1)+(8*4)+(7*2)+(6*8)+(5*8)+(4*8)+(3*3)+(2*5)+(1*3)=197
197 % 10 = 7
So 1428883-53-7 is a valid CAS Registry Number.

Facile syntheses of substituted, conformationally-constrained benzoxazocines and benzazocines via sequential multicomponent assembly and cyclization

Sahn, James J.,Martin, Stephen F.

scheme or table, p. 6855 - 6858 (2012/02/05)

A multicomponent assembly process (MCAP) was utilized to prepare versatile intermediates that are suitably functionalized for subsequent cyclizations via Ullmann and Heck reactions to efficiently construct substituted 2,6-methanobenzo[b][1,5]oxazocines an

Ring-closing metathesis and ring-closing metathesis-isomerisation approach to 1-phosphonylated 2-benzazocines

Dieltiens, Nicolai,Stevens, Christian V.,Masschelein, Kurt,Hennebel, Geert,Van der Jeught, Sarah

, p. 4295 - 4303 (2008/09/19)

An RCM strategy has been developed for the synthesis of phosphonylated benzazocines and their corresponding isomerised analogues. The aminophosphonate precursors were obtained by a one-pot three-component condensation in moderate yield.
