73726-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73726-67-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,2 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73726-67:
(7*7)+(6*3)+(5*7)+(4*2)+(3*6)+(2*6)+(1*7)=147
147 % 10 = 7
So 73726-67-7 is a valid CAS Registry Number.

First synthesis of ventinone A and structural ambiguity of ventinone B
Ray, Sutapa,Mal, Dipakranjan
, p. 833 - 836 (2011/04/22)
Ventinone A, a naturally occurring 1,4-dihydroxyanthraquinone has been synthesized in two steps from known compounds via a Hauser annulation. The same strategy, when applied to the synthesis of ventinone B, reveals that the proposed structure of ventinone
