126265-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126265-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,6 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126265-75:
(8*1)+(7*2)+(6*6)+(5*2)+(4*6)+(3*5)+(2*7)+(1*5)=126
126 % 10 = 6
So 126265-75-6 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF PYRROLIZIDINONES BY RADICAL CYCLIZATION OF N-ALLYLIC PYROGLUTAMATES
Keusenkothen, Paul F.,Smith, Michael B.
, p. 3369 - 3372 (2007/10/02)
Ethyl S-pyroglutamate is converted to N-allylic-S C5-iodomethyl-2-pyrrolidinone.Facile radical cyclization on treatment with AIBN and tributyltin hydride in refluxing benzene gives good yields of the C6 substituted pyrrolizidin-2-one
