914477-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 914477-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,4,4,7 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 914477-77:
(8*9)+(7*1)+(6*4)+(5*4)+(4*7)+(3*7)+(2*7)+(1*7)=193
193 % 10 = 3
So 914477-77-3 is a valid CAS Registry Number.

, p. 5024 - 5029 (2010)
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
