5419-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5419-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5419-51:
(6*5)+(5*4)+(4*1)+(3*9)+(2*5)+(1*1)=92
92 % 10 = 2
So 5419-51-2 is a valid CAS Registry Number.

SYNTHESIS OF 2-PROPYNYL ETHERS OF STEROID ALCOHOLS
Pouzar, Vladimir,Schneiderova, Lenka,Drasar, Pavel,Strouf, Oldrich,Havel, Miroslav
, p. 1888 - 1902 (2007/10/02)
2-Propynyl ethers, derived from steroid alcohols with hydroxyl in position 3β, 17 or 20, were prepared by reaction with propargyl bromide and sodium hydroxide under conditions of phase transfer catalysis.Other hydroxy groups in the steroid molecule were protected with the methoxymethyl or 2-tetrahydropyranyl group.
