Check Digit Verification of cas no

The CAS Registry Mumber 144019-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,0,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144019-19:
(8*1)+(7*4)+(6*4)+(5*0)+(4*1)+(3*9)+(2*1)+(1*9)=102
102 % 10 = 2
So 144019-19-2 is a valid CAS Registry Number.

N-Methyl Allylic Amines from Allylic Alcohols by Mitsunobu Substitution Using N-Boc Ethyl Oxamate

Van Veen, Branca C.,Wales, Steven M.,Clayden, Jonathan

, p. 8538 - 8543 (2021/06/30)

We report the practical, scalable synthesis of a range of N-methyl allylic amines. Primary and secondary allylic alcohols underwent a regioselective Mitsunobu reaction with readily accessible N-Boc ethyl oxamate to deliver the corresponding N-Boc allylic amines, including in enantiopure form via stereospecific substitution. Subsequent N-methylation and Boc deprotection without chromatography yielded the amine products as hydrochloride salts. This method solves the problem of converting commercially available alcohols into often volatile N-methyl allylic amines, many of which have limited commercial availability.

2,3-DISUBSTITUTED 1 -ACYL-4-AMINO-1,2,3,4-TETRAHYDROQUINOLINE DERIVATIVES AND THEIR USE AS BROMODOMAIN INHIBITORS

-

Page/Page column 119, (2014/09/29)

The present invention relates to novel compounds of formula (I), wherein R1 is C1-4alkyl; R2 is C1-4alkyl, C3-7cycloalkyl, -CH2CF3, -CH2OCH3 or heterocyclyl; R3 is C1-4alkyl, -CH2F, -CH2OH or -CH2O(O)CH3; R4 when present is as defined in claim 1; R5 when present is H, halo, hydroxy or C1-6alkoxy; A is -NH-, -O-, -S-, -SO-, -SO2-, -N(C1-4alkyl)- or -NC(O)(CH3)-; V is phenyl, heteroaromatic or pyridone any of which may be optionally substituted by 1, 2 or 3 substituents; W is CH or N; X is C or N; Y is C or N; and Z is CH or N; subject to the proviso that no more than 2 of W, X, Y and Z are N, pharmaceutical compositions containing such compounds and to their use as bromodomain inhibitors.

Aza--Wittig Sigmatropic Rearrangement of Crotyl Amines

Anderson, James C.,Siddons, D. Craig,Smith, Stephen C.,Swarbrick, Martin E.

, p. 1835 - 1836 (2007/10/02)

The first example of an acyclic aza--Wittig sigmatropic rearrangement is presented, and its application to the synthesis of unnatural amino acids is described.
