774559-32-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 774559-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,4,5,5 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 774559-32:
(8*7)+(7*7)+(6*4)+(5*5)+(4*5)+(3*9)+(2*3)+(1*2)=209
209 % 10 = 9
So 774559-32-9 is a valid CAS Registry Number.

Base-catalyzed N -N bond cleavage of hydrazones: Synthesis of α-amino ketones

Tang, Hai-Tao,Zhou, Yun-Bing,Zhu, Yu,Sun, Hong-Chao,Lin, Min,Zhan, Zhuang-Ping

, p. 1278 - 1281 (2014)

An efficient Cs2CO3-promoted synthesis of α-amino ketones using hydrazines, aldehydes, and α-haloketones as starting materials through a cascade condensation/nucleophilic substitution/N -N bond cleavage route is developed. The carbonyl group plays a key role in this novel N -N bond cleavage process. Breaking good: A novel method of base-catalyzed N -N bond cleavage of hydrazones has been discovered. A variety of α-amino ketones was synthesized using hydrazines, α-haloketones, and benzaldehyde as starting materials through a cascade condensation/ nucleophilic substitution/N -N bond cleavage sequence.
