911653-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 911653-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,1,6,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 911653-40:
(8*9)+(7*1)+(6*1)+(5*6)+(4*5)+(3*3)+(2*4)+(1*0)=152
152 % 10 = 2
So 911653-40-2 is a valid CAS Registry Number.

A gold-catalyzed domino process to the steroid framework
Hildebrandt, Dirk,Dyker, Gerald
, p. 6728 - 6733 (2006)
The facile formation of the B and C ring of rac-desoxyequilenin and of a chrysenone derivative in just one preparative step is demonstrated, applying a gold-catalyzed domino process, which involves a benzopyrylium cation as the key intermediate and an int
