Check Digit Verification of cas no

The CAS Registry Mumber 114943-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,9,4 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 114943-74:
(8*1)+(7*1)+(6*4)+(5*9)+(4*4)+(3*3)+(2*7)+(1*4)=127
127 % 10 = 7
So 114943-74-7 is a valid CAS Registry Number.

Organocatalytic trans Phosphinoboration of Internal Alkynes

Fritzemeier, Russell G.,Nekvinda, Jan,Rosenblum, Carol Ann,Santos, Webster L.,Slebodnick, Carla,Vogels, Christopher M.,Westcott, Stephen A.

supporting information, p. 14358 - 14362 (2020/07/04)

We report the first trans phosphinoboration of internal alkynes. With an organophosphine catalyst, alkynoate esters and the phosphinoboronate Ph2P-Bpin are efficiently converted into the corresponding trans-α-phosphino-β-boryl acrylate products in moderate to good yield with high regio- and Z-selectivity. This reaction operates under mild conditions and demonstrates good atom economy, requiring only a modest excess of the phosphinoboronate. X-ray crystallography experiments allowed structural assignment of the unprecedented and densely functionalized (Z)-α-phosphino-β-boryl acrylate products.

Synthesis of 2-amino-6-phenyl-4H-pyran-4-ones

Morris,Wishka

, p. 43 - 46 (2007/10/02)

The treatment of a series of phenylacetylenic β-keto amides with methanesulfonic acid produces a high yielding intramolecular cyclization to the corresponding 2-amino-6-phenyl-4H-pyran-4-ones.
