126374-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126374-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,7 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 126374-06:
(8*1)+(7*2)+(6*6)+(5*3)+(4*7)+(3*4)+(2*0)+(1*6)=119
119 % 10 = 9
So 126374-06-9 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
