854423-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 854423-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,4,2 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 854423-41:
(8*8)+(7*5)+(6*4)+(5*4)+(4*2)+(3*3)+(2*4)+(1*1)=169
169 % 10 = 9
So 854423-41-9 is a valid CAS Registry Number.

An effective method for the synthesis of 13C-labeled polyprenylhydroxybenzoic acids
Lang, Martin,Steglich, Wolfgang
, p. 1019 - 1027 (2007/10/03)
The synthesis of side-chain 13C-labeled geranylgeranyl-4- hydroxybenzoic acids and geranylgeranyl-3,4-dihydroxybenzoic acids is described. The synthesis starts from O-protected methyl hydroxyiodobenzoates, which are transformed into Grignard re
