1262241-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262241-04-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,4 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1262241-04:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*4)+(3*1)+(2*0)+(1*4)=112
112 % 10 = 2
So 1262241-04-2 is a valid CAS Registry Number.

Resolution of (4RS,5RS)-4,5-diphenylimidazolidine-2-thione using pentafluorophenyl active esters
Andreou, Anna,Shaye, Najla Al,Brown, Hannah,Eames, Jason
, p. 6935 - 6938 (2011/03/18)
(4RS,5RS)-4,5-Diphenylimidazolidine-2-thione is resolved efficiently by treatment with NaHMDS and an enantiomerically pure pentafluorophenyl active ester. The levels of diastereocontrol were excellent (up to 90% de).
