129027-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129027-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129027-57:
(8*1)+(7*2)+(6*9)+(5*0)+(4*2)+(3*7)+(2*5)+(1*7)=122
122 % 10 = 2
So 129027-57-2 is a valid CAS Registry Number.

Replacement of Aryl by Alkyl in 1-Substituted 1H-1,2,3-Triazole-4-carbaldehydes
L'abbe, Gerrit,Bruynseels, Maria
, p. 1492 - 1493 (2007/10/02)
1-Phenyl-1,2,3-triazole-4-carbaldehyde is readily transformed into 1-alkyl-1,2,3-triazole-4-carbaldehydes by thermal isomerization of the corresponding imines, followed by acid hydrolysis.
