General Description
[(dimethylamino)methylene]dimethylammonium methyl sulphate is a chemical compound with the molecular formula (CH3)2NCH2N(CH3)2CH3SO4. It is a quaternary ammonium salt, which means it contains a positively charged nitrogen atom bonded to four alkyl or aryl groups. [(dimethylamino)methylene]dimethylammonium methyl sulphate is commonly used as a phase-transfer catalyst in organic synthesis reactions, where it facilitates the transfer of a reactant from one phase to another, allowing the reaction to proceed more efficiently. It is also used as a stabilizer for certain types of polymers and as a reactant in the production of other chemicals. However, it is important to handle this compound with caution as it is a potential irritant and can cause respiratory issues if inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 2013-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,1 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2013-91:
(6*2)+(5*0)+(4*1)+(3*3)+(2*9)+(1*1)=44
44 % 10 = 4
So 2013-91-4 is a valid CAS Registry Number.

NEW PROCESSES
-
Page/Page column 135, (2009/08/16)
The invention relates to a new process for producing NEP inhibitors or prodrugs thereof, in particular NEP inhibitors comprising a γ-amino-δ-biphenyl-α-methylalkanoic acid, or acid ester, backbone. In detail, the new processes, according to the present invention, are ultimately related to the synthesis of intermediates to prepare the above NEP inhibitors, namely compounds according to formula (1), or salt thereof, wherein R1 and R2 are, independently of each other, hydrogen or a nitrogen protecting group, and R3 is a carboxyl group or an ester group, preferably carboxyl group or alkyl ester.
