134786-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134786-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,8 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134786-20:
(8*1)+(7*3)+(6*4)+(5*7)+(4*8)+(3*6)+(2*2)+(1*0)=142
142 % 10 = 2
So 134786-20-2 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
