104799-51-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104799-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,9 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104799-51:
(8*1)+(7*0)+(6*4)+(5*7)+(4*9)+(3*9)+(2*5)+(1*1)=141
141 % 10 = 1
So 104799-51-1 is a valid CAS Registry Number.

The structure of aurantioemestrin (1), a new degradated dioxopiperazine isolated from Emericella striata (80-NE-22), was established as 1 on the basis of spectroscopic evidences.Aurantioemestrin (1), a dioxopiperazinethione, seems to be the biogenetical key intermediate from emestrin (3) to dethiosecoemestrin (2).
