Check Digit Verification of cas no

The CAS Registry Mumber 73536-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,3 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73536-69:
(7*7)+(6*3)+(5*5)+(4*3)+(3*6)+(2*6)+(1*9)=143
143 % 10 = 3
So 73536-69-3 is a valid CAS Registry Number.

Multi-functionalization of gallic acid towards improved synthesis of α- and β-DDB

Alam, Ashraful,Takaguchi, Yutaka,Ito, Hideyuki,Yoshida, Takashi,Tsuboi, Sadao

, p. 1909 - 1918 (2007/10/03)

The synthesis of mono-, di- and trisubstituted gallic acids and their ester with similar or different groups including different acetal and ketals is described. Regioselective bromination on two ortho-positions of methyl gallate, which is very crucial for many organic syntheses, was achieved in high yield and purity. The α- and β-DDB were synthesized in high overall yield and purity from the regioselective bromoderivatives.

New synthesis of (S)-dimethyl-4,4′-dimethoxy-5,6,5′,6′- dimethenedioxy-biphenyl-2,2′-dicarboxylate by configuration transform

Cheng, Sen-Xiang,Chang, Jun-Biao,Qu, Ling-Bo,Chen, Rong-Feng

, p. 1665 - 1667 (2007/10/03)

(R/S)-4,4′-Dimethoxy-5,6,5′,6′-dimethenedioxy-2, 2′-di-(4(S)-methyl-oxazoline-1)-biphenyl has been synthesized from dimethyl-4,4′-dimethoxy-5,6,5′,6′-dimethenedioxy-biphenyl-2, 2′-dicarboxylate, and then the diastereoisomer mixture was almost fully converted to a single diastereoisomer with S-configuration ((S)-3) through the key configuration transform promoted by CuI, which was confirmed by CD, HPLC and 13C NMR. The C2-symmetric biphenyl, (S)-dimethyl-4,4′-dimethoxy-5,6,5′,6′-dimethenedioxy-biphenyl- 2,2′-dicarboxylate was prepared easily via the hydrolysis and ester exchange of (S)-3.

Synthesis and antihepatotoxicity of some Wuweizisu analogues

Wu,Chen,Chang,Chen,Lee

, p. 353 - 358 (2007/10/02)

A preparation of dimethyl 4,4'-dimethoxy-5,6,5',6'-dimethylenedioxybiphenyl-2,2'-dicarboxylate (VII) was readily achieved. It provided the advantages of specificity, simplicity, and efficiency in reactions. 6-Phenyl-3,9-dimethoxy-1,2-methylenedioxy-10,11-methylenedioxy-6,7- dihydro-5H-dibenz(c, e)azepin (X) was successfully synthesized from VII (DDB) and its liver-protective property proved to be more effective than DDB and silymarin in the in vitro test of carbon tetrachloride-induced damage of primary cultured rat hepatocytes.
