508195-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 508195-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,8,1,9 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 508195-74:
(8*5)+(7*0)+(6*8)+(5*1)+(4*9)+(3*5)+(2*7)+(1*4)=162
162 % 10 = 2
So 508195-74-2 is a valid CAS Registry Number.

Direct conversion of acetals to esters with high regioselectivity via O,P-acetals
Maegawa, Tomohiro,Otake, Kazuki,Goto, Akihiro,Fujioka, Hiromichi
, p. 5648 - 5651 (2011)
A new direct conversion of O,O-acetals to esters via O,P-acetal intermediates was developed. The regioselective cleavage of unsymmetrical cyclic acetals occurred to give the more crowded esters as single isomers.
