103462-30-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103462-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,6 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103462-30:
(8*1)+(7*0)+(6*3)+(5*4)+(4*6)+(3*2)+(2*3)+(1*0)=82
82 % 10 = 2
So 103462-30-2 is a valid CAS Registry Number.

REVISED STRUCTURE OF A FLAVONOID FROM THE FERN NOTHOLAENA ASCHENBORNIANA

Iinuma, M.,Fang, N.,Tanaka, T.,Mizuno, M.,Mabry, T. J.,et al.

, p. 1257 - 1258 (2007/10/02)

The structure of a flavonoid from the fern Notholaena aschenborniana, previously described as 5,4',6'-trihydroxy-6,7,2',3'-tetramethoxyflavone, is revised to 5,2',4'-trihydroxy-3,7,8,5'-tetramethoxyflavone on the basis of current studies on 2'-oxygenated flavonoids.Identity of the natural product with the proposed structure is confirmed by synthesis. Key Word Index - Notholaena aschenborniana; Pteridophyta; Polypodiaceae; 5,2',4'-trihydroxy-3,7,8,5'-tetramethoxyflavone; synthesis.
