Check Digit Verification of cas no
The CAS Registry Mumber 21855-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21855-46:
(7*2)+(6*1)+(5*8)+(4*5)+(3*5)+(2*4)+(1*6)=109
109 % 10 = 9
So 21855-46-9 is a valid CAS Registry Number.

Diastereoselective synthesis of a methylated derivative of phomozin, a phytotoxin isolated from phonopsis helianthi, a phytopathogenic fungus of sunflowers
Nouguier,Bertrand,Picon,Perfetti
, p. 8171 - 8172 (2007/10/02)
A methylated derivative of the phytotoxin phomozin (2) is synthesized in high yield via the regioselective coupling of 2-methyl-4-benzyl orsellinic acid (6) and (R*, R*) benzyl dimethylglycerate (9) and one step hydrogenolysis of the benzyl and benzoyl protection.
Synthesis and Regiospecific Deoxygenation of β-Resorcylic Ester Derivatives to 4-Hydroxybenzoates
Bartlett, Alan J.,Holker, John S.E.,O'Brien, Eugene
, p. 667 - 670 (2007/10/02)
Ethyl -4-hydroxy-2-methyl- (6a), and -2,3,5-trimethyl-benzoate (6b), together with ethyl 4-hydroxy-2,3-dimethylbenzoate (6c), have been prepared in satisfactory yields by deoxygenation of the corresponding resorcylate esters, (5a-c), respectively, via hydrogenolysis of their 4-benzyloxy-2-(1-phenyl-1H-tetrazolyloxy)-derivatives, (8a-c).Ethyl 2,4-dihydroxy-5,6-dimethyl-3-trideuterio-methylbenzoate (5d) has been synthesised by trideuteriomethylation of ethyl 2,3-dimethyl-4,6-dioxocyclohexanecarboxylate (10c), followed by dehydrogenation.Preparation of the requisite resorcylate derivatives are included.
