67492-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67492-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,9 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67492-31:
(7*6)+(6*7)+(5*4)+(4*9)+(3*2)+(2*3)+(1*1)=153
153 % 10 = 3
So 67492-31-3 is a valid CAS Registry Number.

Synthesis of Naturally Occurring (+/-)-7,3'-Dihydroxy-4'-methoxyisoflavanone and Some Isoflavanones Related to Natural 6,7-Dimethoxy-3',4'-methylenedioxyisoflavanone

Jain, A. C.,Bambah, P. K.

, p. 628 - 633 (2007/10/02)

2,4,3'-Trihydroxy-4'-methoxydesoxybenzoin (2) on treatment with two mol of ethoxymethyl chloride followed by one mol of ethoxymethyl chloride yields the α-hydroxyketone (4) which undergoes cyclization with 4 percent EtOH-Na2CO3 to afford 7,3'-diethoxymethoxy-4'-methoxyisoflavanone (5).Deprotection of 5 with 10 percent MeOH-HCl yields the naturally occurring 7,3'-dihydroxy-4'-methoxyisoflavanone (1a).Similarly 7-methoxy-3',4'-methylenedioxy-(9a)-, 5,7-dimethoxy-3',4'-methylenedioxy-(9b), 6,7-dimethoxy-(9c), and 7-hydroxy-3',4'-methylenedioxy-(14)-isoflavanones have been synthesized starting from the corresponding desoxybenzoins (7a, 7b, 7c and 10 respectively) via α-hydroxymethylation to yield the carbinols (8a, 8b, 8c and 12 respectively) and then cyclization to give the corresponding isoflavanones.The isoflavanone 14 is obtained by treating 13 with 10 percent MeOH-HCl.
