General Description
2,4-Dibromopyridine-3-carboxaldehyde is an organic compound and a derivative of pyridine, with the molecular formula C6H3Br2NO. This yellow solid chemical is well-known in chemistry for its broad usage in organic synthesis thanks to its bifunctionality. Among its most remarkable features are two bromine atoms on its 2nd and 4th carbons and an aldehyde functional group at the 3rd position. With these, it can perform two different chemical reactions simultaneously on one molecule, making it a highly efficient reagent for several types of reactions including, but not limited to, aldol condensation, Wittig reaction, and Grignard reaction.
Check Digit Verification of cas no
The CAS Registry Mumber 128071-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128071-91:
(8*1)+(7*2)+(6*8)+(5*0)+(4*7)+(3*1)+(2*9)+(1*1)=120
120 % 10 = 0
So 128071-91-0 is a valid CAS Registry Number.
