124789-72-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124789-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,8 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124789-72:
(8*1)+(7*2)+(6*4)+(5*7)+(4*8)+(3*9)+(2*7)+(1*2)=156
156 % 10 = 6
So 124789-72-6 is a valid CAS Registry Number.

3-Silaazetidine: An Unexplored yet Versatile Organosilane Species for Ring Expansion toward Silaazacycles

Small-ring silacycles are important organosilane species in main-group chemistry and have found numerous applications in organic synthesis. 3-Silaazetidine, a unique small silacycle bearing silicon and nitrogen atoms, has not been adequately explored due to the lack of a general synthetic scheme and its sensitivity to air. Here, we describe that 3-silaazetidine can be easily prepared in situ from diverse air-stable precursors (RSO2NHCH2SiR12CH2Cl). 3-Silaazetidine shows excellent functional group tolerance in a palladium-catalyzed ring expansion reaction with terminal alkynes, giving 3-silatetrahydropyridines and diverse silaazacycle derivatives, which are promising ring frameworks for the discovery of Si-containing functional molecules.

Various prochirals silapropan-diols were synthetised with good yields. Several enzymatic-catalysed hydrolyses or transesterification have been attempted on this products; when we change the parameters: as the temperature in transesterification reaction, t
