1236306-02-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1236306-02-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,3,0 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1236306-02:
(9*1)+(8*2)+(7*3)+(6*6)+(5*3)+(4*0)+(3*6)+(2*0)+(1*2)=117
117 % 10 = 7
So 1236306-02-7 is a valid CAS Registry Number.

On reactions of spirostane sapogenins with benzeneseleninic anhydride
Jastrzbska, Izabella,Dobrogowska, Aneta,Lutostańska, Ewa,Morzycki, Jacek W.
experimental part, p. 5024 - 5029 (2010/08/20)
Direct dehydrogenation of spirostane sapogenins with benzeneseleninic anhydride/iodoxybenzene afforded the Δ22 derivatives in low yields. The reactions catalyzed by BF3/Et2O produced the 23-oxo-sapogenins in addition to th
