74991-35-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74991-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,9 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74991-35:
(7*7)+(6*4)+(5*9)+(4*9)+(3*1)+(2*3)+(1*5)=168
168 % 10 = 8
So 74991-35-8 is a valid CAS Registry Number.

Wavelength-dependent optoacoustic imaging probes for NMDA receptor visualisation

Sim, Neil,Gottschalk, Sven,Pal, Robert,Delbianco, Martina,Degtyaruk, Oleksiy,Razansky, Daniel,Westmeyer, Gil G.,Ntziachristos, Vasilis,Parker, David,Mishra, Anurag

, p. 15149 - 15152 (2015/10/12)

The cellular localisation and binding specificity of two NMDAR-targeted near-IR imaging probes has been examined by microscopy, followed by exemplification of MSOT to monitor simulated glutamate bursts in cellulo and a preliminary study in mice observing the signal in the brain.

THE STEREOSELECTIVE REDUCTION OF α-AMINOPROPIOPHENONE DERIVATIVES WITH SODIUM BOROHYDRIDE

Kametani, Tetsuji,Kigasawa, Kazuo,Hiiragi, Mineharu,Wagatsuma, Nagatoshi,Kohagizawa, Toshitaka,Inoue, Hitoshi

, p. 775 - 778 (2007/10/02)

The ratio of erythro and threo products from the sodium borohydride reduction of the hydrochlorides, and other acid salts, of α-aminopropiophenone derivatives was determined.It was found that this procedure resulted in stereoselective formation of erythro-2-amino-1-phenylpropanols in contrast to sodium borohydride reduction of the corresponding free bases.The method was successfully applied to the synthesis of dl-erythro-2-(4-benzylpiperidino)-1-(4-hydroxyphenyl)propanol which has been used as a vasodilator.
