Check Digit Verification of cas no

The CAS Registry Mumber 518308-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,8,3,0 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 518308-79:
(8*5)+(7*1)+(6*8)+(5*3)+(4*0)+(3*8)+(2*7)+(1*9)=157
157 % 10 = 7
So 518308-79-7 is a valid CAS Registry Number.

Substituent-dictated concise synthesis of 4,6-disubstituted N-alkyl-2-pyridones and 2-aminopyridines

Goel, Atul,Singh, Fateh V.,Verma, Deepti

, p. 2027 - 2030 (2005)

Functionalized N-alkyl-2-pyridones and 2-aminopyridines are useful precursors for the synthesis of various heterocyclic compounds of therapeutic importance. In this paper we have delineated and illustrated a direct methodology for the synthesis of 6-aryl-

Synthesis, spectral characterization and photophysical studies of tetrahydroquinolines

Kennedy, L. John,Singh, Fateh V.,Subashini, C.

, (2020/10/18)

A metal-free, ultrasound-assisted, fast synthesis of fluorescent N-Boc-protected 1,2,3,4–tetrahydroquinolines 9a-p is described through carbanion-induced ring transformation of 6-aryl-2H-pyran-2-ones 7 with tert?butyl 3-oxopiperidine-1-carboxylate 8 under

Base-promoted regioselective synthesis of 1,2,3,4-terahydroquinolines and quinolines from N-boc-3-piperidone

Shally,Althagafi, Ismail,Singhal, Divya,Panwar, Rahul,Shaw, Ranjay,Elagamy, Amr,Pratap, Ramendra

, (2019/11/11)

An efficient synthesis of 1,2,3,4-tetrahydroquinolines with donor and acceptor group has been delineated by base mediated ring transformation of 6-aryl-4-substituted-2H-pyran-2-one-3-carbonitriles by N-boc-3-piperidone followed by consecutive deprotection
