72335-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72335-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,3 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72335-77:
(7*7)+(6*2)+(5*3)+(4*3)+(3*5)+(2*7)+(1*7)=124
124 % 10 = 4
So 72335-77-4 is a valid CAS Registry Number.

CYCLISATION DE N-TOSYL OXIRANES-PROPYLAMINES: SYNTHESE D'HETEROCYCLES AZOTES.
Nuhrich, A.,Moulines, J.
, p. 3075 - 3088 (2007/10/02)
The cyclisation of N-tosyl-oxiranepropylamines is accomplished in aqueous basic medium and in anhydrous acid medium as well.In most cases, this reaction occurs by a regiospecific 5-exo-tet. ring closure and affords N-tosyl-2-pyrrolidinemethanols in high y
