129144-73-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129144-73-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,4 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129144-73:
(8*1)+(7*2)+(6*9)+(5*1)+(4*4)+(3*4)+(2*7)+(1*3)=126
126 % 10 = 6
So 129144-73-6 is a valid CAS Registry Number.

Reactivity of polyvinylogation: Easy and rapid access to different polyenals
Ramondenc,Ple
, p. 10855 - 10876 (2007/10/02)
This work describes the synthesis and the reactivity of three reagents of polyvinylogation 1-3. By condensation with several aldehydes and ketones, these reagents allow the introduction of three or four doubles bonds, leading to polyenals 5-6 in one or tw
