1026190-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026190-77-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,1,9 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1026190-77:
(9*1)+(8*0)+(7*2)+(6*6)+(5*1)+(4*9)+(3*0)+(2*7)+(1*7)=121
121 % 10 = 1
So 1026190-77-1 is a valid CAS Registry Number.

Resolution of Hydroxyureas
Garigipati, Ravi S.,Sorenson, Margaret E.,Erhard, Karl F.,Adams, Jerry L.
, p. 5537 - 5540 (1993)
Racemic hydroxyureas can be efficiently resolved on a preparative scale using (4S)- 4-benzyl-2-oxazolidine-3-carbonyl chloride 3.The resulting carbamates can be separated by chromatography and hydrolysis of these diastereomers yields enantiomerically pure hydroxyureas.
