129378-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129378-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,7 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129378-59:
(8*1)+(7*2)+(6*9)+(5*3)+(4*7)+(3*8)+(2*5)+(1*9)=162
162 % 10 = 2
So 129378-59-2 is a valid CAS Registry Number.

2-Protecting Groups for 5-Lithiation in the Synthesis of Imidazoles
Ngochindo, Raphael I.
, p. 1645 - 1648 (2007/10/02)
Various substituents have been examined as possible 2-protecting groups against organolithium reagents in the syntheses of imidazoles on the basis of the ease of decarboxylation of imidazole-2-carboxylic acids and cleavage of the C(2)-Si bond.The tertiary
