138370-18-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138370-18-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,7 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138370-18:
(8*1)+(7*3)+(6*8)+(5*3)+(4*7)+(3*0)+(2*1)+(1*8)=130
130 % 10 = 0
So 138370-18-0 is a valid CAS Registry Number.

A Synthesis of Emodin Anthrone
Falk, Heinz,Schoppel, Gerhard
, p. 739 - 744 (2007/10/02)
A novel high yield (74percent overall) synthesis of five steps to prepare emodin anthrone, which serves as a valuable precursor of hypericin, was devised using the benzamide ortho lithiation strategy for the key step. Keywords.Emodin anthrone; Hypericin;
