Check Digit Verification of cas no

The CAS Registry Mumber 77744-13-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,4 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77744-13:
(7*7)+(6*7)+(5*7)+(4*4)+(3*4)+(2*1)+(1*3)=159
159 % 10 = 9
So 77744-13-9 is a valid CAS Registry Number.

Visible-Light Photocatalytic Difluoroalkylation-Induced 1, 2-Heteroarene Migration of Allylic Alcohols in Batch and Flow

Wei, Xiao-Jing,No?l, Timothy

, p. 11377 - 11384 (2018)

A convenient method for the preparation of sp3-rich heterocycles is reported. The method comprises a photocatalytic difluoroalkylation-induced 1,2-heteroarene migration of allylic alcohols. Here we describe for the first time the benefits of us

Synthesis of 3-Aryl-3-pyridylallylamines Related to Zimelidine via Palladium-Catalyzed Amination

Baeckvall, Jan-E.,Nordberg, Ruth E.,Nystroem, Jan-E.,Hoegberg, Thomas,Ulff, Bengt

, p. 3479 - 3483 (2007/10/02)

Reaction of aryl pyridyl ketones 1 with vinylmagnesium bromide followed by acetylation of the products 2 with acetic anhydride/Et3N and with 4-(dimethylamino)pyridine (DMAP) as a catalyst gave acetates 3 in high yields.Treatment of acetates 3 with dimethylamine in the presence of a palladium catalyst produced a mixture of E and Z isomers of 3-aryl-3-pyridylallylamines 4.
