934815-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 934815-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,8,1 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 934815-40:
(8*9)+(7*3)+(6*4)+(5*8)+(4*1)+(3*5)+(2*4)+(1*0)=184
184 % 10 = 4
So 934815-40-4 is a valid CAS Registry Number.

New syntheses of dalbergichromene and dalbergin from vanillin via neoflavene intermediate

Li, Sie-Rong,Chen, Liang-Yeu,Tsai, Jui-Chi,Tzeng, Jing-Yu,Tsai, Ian-Lih,Wang, Eng-Chi

, p. 2139 - 2141 (2008/02/08)

In this Letter, naturally occurring dalbergichromene and dalbergin were synthesized from a common neoflavene intermediate, which was derived from vanillin. The giving neoflavene intermediate was debenzylated with AlCl3 to yield dalbergichromene in 39% total yield, and it was oxidized by DDQ, and subsequently debenzylated by Pd(OH)2/C and cyclohexene in refluxing ethanol to give dalbergin in 31% total yield.
